LINKMICRO LM407 Digital Microscope Review

Godlygamer23 · January 2, 2023

Hi all,

I recently purchased a digital microscope from Amazon. The microscope cost me about $153, and I purchased it to replace a camera microscope that I was using that required a functional computer. Below is my review of the microscope. I also apologize for formatting. The forum software was not cooperating with me.

TLDR: The microscope is decent, especially for the money. It is plagued by certain limitations, mostly dealing with how far you can actually zoom out, and compression that occurs on captured images.

I have already unpacked and used this microscope before I considered doing a review on the forum, so I have no unboxing photos. With that being said, the boxes the microscope came in were generic cardboard boxes, but the packaging was pretty decent. It kept everything safe in transit, and the foam that was used was high quality soft foam. Assembly wasn't too difficult. The display/camera itself sits in a ring held with two thumbscrews. The main mount attaches to the platform with two Allen head screws. The required Allen key also comes with the microscope.

View of microscope assembled:

The display is on the top, with two bright LED bulbs that flank it. You can move them around as needed, and adjust the brightness with the included control buttons, as you'll see next.

Rear of display, also showcasing the control buttons that allow you to power off the entire microscope, including the LED bulbs:

Spoiler

The control panel has a micro-USB cable that connects to the display, as well as a plug that inserts into the base to power the LED bulbs. The very end of the harness ends with a USB type-A connector. The microscope comes with a wall adapter that doesn't feel very substantial, so I've elected to plug it into my test bench and power it off of the 5V rail. See next photo for that section of the base.

Spoiler

The digital microscope comes with a remote that is alright, but feels cheap, and can be difficult to aim towards the infrared sensor. It is what allows you to access the menu system of the microscope, which allows you to make various adjustments, including exposure, resolution, etc. You can also use it to take pictures, which allows you to avoid the shakiness of pressing the button the display.

Which leads us into the display itself, including what the menu interface looks like:

Spoiler

The buttons allow you to power on/off the microscope(if you wanna use the LEDs independently from the microscope), change the mode(you can use this to review stored footage), perform a digital zoom, or if you click OK, it will start recording video. The camera button will snap a picture. There is also a knob a little above the ring that allows you to adjust focus.

Here's the base itself. I applied tape to the base to prevent damage to itself, as well as anything I put on it. It did not come like this.

Spoiler

There are some vacant mounting holes in the base - this microscope comes with these little metal "fingers"(lol) that allow you to set items onto. I found them to be more of a hindrance than anything else, so I removed them. I have them shown in the next photo.

And now we get into the various images that I've taken with the microscope:

Spoiler

Overall, it is pretty decent. Obviously, you can see a lot of detail, and the pictures look pretty clear. However, there are times where I think there is compression on the photos that show, particularly when you zoom in, even a little bit. Otherwise, they're decent photos.

Overall, the microscope is pretty capable, but it is plagued by limitations when it comes to usage. The camera, at its highest point, is very zoomed in. There is no physical zoom to adjust, so in order to zoom, you need to either deal with using digital zoom, or physically move the camera down, and refocus it. For the price, I think it's worth it.
