ISM-DL300 or ISM-DL301: Which Digital Microscope Do You Need?
Both models share the same optics, camera, LCD and software. The only difference is lighting. If you need to measure outlines, holes or edge distances, you need the contour (base) light on the ISM-DL301.
ISM-DL300
For surface inspection: tool wear, scratches, markings and solder joints.
- Ring light (surface)
- Backlight
- Inspect and measure features visible from above
- Best for opaque parts and surface defects
ISM-DL301
Adds contour measurement: profiles, apertures and edge dimensions.
- Ring light (surface)
- Backlight (base)
- Backlit silhouette gives a sharp edge for automatic edge finding
- Separate brightness control for ring and contour light
Not sure? INSIZE recommends the ISM-DL301 whenever you measure workpiece contours, because the backlit edge is advantageous and produces accurate measurements.

Many factory measurement microscopes come as a set of separate units: the microscope itself, a monitor, a computer and independently installed software. Over time, configurations become more complex and workshops fill with oil and dust. This time we recommended the INSIZE ISM-DL301 digital measuring microscope to our client. Their needs were simple: clear visuals, accurate measurements and straightforward operation.
The ISM-DL301 has built-in measurement software, so there is no need for an external computer. Just plug it in and start working. Quality inspectors can be trained and ready in 30 minutes.
What matters most is what you are measuring. To inspect surface details or tool-edge wear, switch on the ring light for a crystal-clear view. To measure contours, apertures and edge dimensions, turn on the base illumination, place the workpiece and the contour appears instantly. The software includes multiple tools for one-click measurement of different dimensions.
With a continuous zoom lens, parts of different sizes can be measured in the ideal field of view. Measurement data can be exported to Excel in one click, and inspection images saved directly to a USB drive, keeping quality control in step with production wherever it goes.
When we recommend equipment, we don’t just talk about how advanced a microscope is. We recommend a solution tailored to your workpieces, inspection process and requirements. If you have parts that are difficult or cumbersome to measure, send them to us and we will help you find the best way to measure them.

Machined and stamped parts
Hole diameters and positions, slot widths, threads and radii.
Electronics and PCB
Solder joint inspection and component lead spacing.
Moulds and cutting tools
Tool-edge wear and chipping, cavity and insert dimensions.
Rubber and plastic parts
Seal and O-ring profiles, injection-moulded features.
Digital Microscope vs Profile Projector vs VMM
Three optical ways to measure small parts. The right one depends on part size, how many features you check and how you need to record results.
| What to compare | Digital microscope (ISM-DL301) | Profile projector | Vision measuring machine (VMM) |
|---|---|---|---|
| How it works | A camera and zoom lens show a live image on an LCD. Built-in software measures on screen. | Optics project a magnified silhouette or surface image onto a large screen. You measure against the screen or with a stage readout. | A camera, motorised stage and software measure automatically, often with laser or touch-probe options. |
| Typical parts | Small, flat parts and features that fit in one field of view (up to 16 mm). | Outlines and profiles of small to medium flat parts, such as threads, gears and stampings. | Larger parts, many features and 3D geometry. |
| How you measure | Manually, one click per feature, with automatic edge finding. | Manually. The operator lines up edges with crosshairs or an overlay chart. | Automatically. A programmed routine measures features in sequence. |
| Recording results | Excel export and saved images. | Depends on the readout. Often written down by hand or sent from an optional data processor. | Full reports and data export from the measuring software. |
| Operator skill | Low. Inspectors can be trained in about 30 minutes. | Moderate. Results depend on how the operator aligns edges. | Higher. Automatic routines need programming. |
| Footprint | Benchtop: 570 × 300 × 430 mm, 6.5 kg. | Benchtop or floor-standing, usually bulkier because of the projection screen. | Benchtop or floor-standing, the largest of the three. |
| Best when | You need quick, recorded checks of small features at the bench. | Your process already uses projector methods and overlay charts. | You measure batches, large parts or 3D features. |
Need automatic 2D measurement of many features without programming? See the Quick Measurement System. For 3D and multi-sensor measurement of larger parts, see the CNC vision measuring machine.
Recommended with This Digital Microscope
Add precise positioning for small features, or step up to automatic measurement for larger parts and batches.
Recommended accessory

Digital Microscope FAQ
Can’t find your answer? Ask our applications team.
What is a digital microscope used for?
In manufacturing, a digital measuring microscope is used to inspect and measure small features on a screen: hole diameters and positions, slot widths, radii and angles on machined and stamped parts; solder joints and lead spacing on PCBs; edge wear and chipping on cutting tools; and seal and O-ring profiles. Images and measurement results can be saved for QC records.
Do I need a computer to use the ISM-DL300 or ISM-DL301?
No. The measurement software is built into the microscope and operated with a mouse, and a 13.3-inch LCD is included, so there is no PC, software installation or licence to manage.
What is the difference between the ISM-DL300 and ISM-DL301?
The ISM-DL301 adds a contour (base) light source under the stage for outline and profile measurement. The ISM-DL300 has the LED ring light only. For profile dimension measurement, choose the ISM-DL301.
What is a digital measuring microscope?
A digital measuring microscope combines zoom optics, a digital camera and measurement software, so you can see and measure small features on screen instead of by eye. The INSIZE ISM-DL300 and ISM-DL301 run the software inside the unit and display on the included 13.3-inch LCD, so no PC is needed. They magnify from 15X to 100X, measure down to ±4 µm and send results to Excel. Choose the ISM-DL301 if you measure contours or profiles.
How accurate is the ISM-DL300 series?
Accuracy depends on magnification: ±8 µm at 15X, improving to ±4 µm at 80X–100X. Automatic edge finding locates the measurement edges for you, which reduces manual measurement error.
Are digital microscopes better than traditional measuring microscopes?
It depends on the part and the job. A digital measuring microscope shows the magnified image on a screen, so you measure with software tools instead of an eyepiece reticle, save images and export results to Excel. For small, flat parts that fit in one field of view (up to 16 mm on the ISM-DL300 series), that makes inspection quicker to learn and easier to record. For larger parts, many features or batch inspection, a Quick Measurement System or vision measuring machine is usually a better fit.
What is the largest part I can measure in one field of view?
The maximum measurable length in a single field of view is 16 mm, with a standard field of view of up to 16 × 11 mm. For larger parts, a Quick Measurement System or vision measuring machine is a better fit.
Can I export measurement results to Excel?
Yes. Measurement results can be sent to Excel, and inspection images save directly to the included 16 GB USB flash disk.
Can I increase the magnification beyond 100X?
Yes. With the optional 1X camera adapter or 2X auxiliary objective, magnification extends to 200X, or up to 400X with both.
Why does the image look reddish, bluish or yellowish?
This is usually incorrect white balance. Place white paper or a white board over the whole field of view, then use Auto White Balance to correct the colour.
The measurement area is small and moving the part by hand causes errors. What do you recommend?
Add the X-Y metal stage (ISM-DL-STAGE1). Its adjustment knobs position the part precisely in X and Y, so you do not need to move it by hand.
Can I get a demo, sample testing or a trial unit in Malaysia?
Yes. Alloytool (M) Sdn Bhd, the INSIZE partner in Malaysia, offers on-site or virtual demonstrations, sample testing with a results report, and trial units, with offices in Kuala Lumpur, Penang and Johor.
How much does a digital measuring microscope cost in Malaysia?
The price depends on the model (ISM-DL300 or ISM-DL301) and any optional lenses or X-Y stage. Alloytool (M) Sdn Bhd, the INSIZE partner in Malaysia, quotes in ringgit. Request a quote or call +60 12-395 6288.
