Question

I bought a digital microscope fromDinolite, modelAM73915MZT, The use of the microscope is for industries like textiles and printing and graphics and for Ophthalmology / Iridology and Pathology[And as it says on the website that the manufacturer of this microscope is suitable for another wide range of applications]. As shown on the manufacturer's websitehereThe camera has a resolution of5 Megapixel (2592x1944), and the sensor is of theCMOStype, with whiteLEDlighting, includingPolarizer. The microscope costs $1469 before VAT and ancillary aids. From what I understand it is the best and most advanced model of this company. I took some pictures with him, and at 220x magnification I can't get a sharp enough picture.

Attached an image of thecalibration targetprovided by the company along with the microscope. Image at a magnification of 220- 10 barcodes Image at magnification of 50- 10 barcodes [marked with a red line] You can see that the edges of the barcodes at magnification 220 times are not sharp compared to the edges at magnification 50 times.
Does this mean that the microscope is unprofessional or damaged and I need to replace it?
Is it related toSpherical aberration? EDIT: Both photos were taken with the microscope standing in the best stand of the company, modelRK-10A.If I rotate theadjustment knobslightly to
the right or left, the image only becomes more blurred, which means
that the position in the image is the maximum sharpness.And for that I wonder if a microscope that this is its maximum sharpness - is considered professional. EDIT 2: Attached image of a scratch: 51x 228x You can see that the 51x image is much sharper and crispier compared to the 228x image, does that mean that the microscope is neither high quality nor professional? Razor 50x 229x Basically you have bought a basic microscope that is not very good, with probably poor quality lenses and low manufacturing quality - the fact that they don't mention the lens manufacturer is a sign that has cheaper lens(es). A lack of reviews on microscopy sites also indicates that it is not well known. It may be suitable for basic hobbyist use-cases, and depending on what you want to do with it, it may suit you. Despite the blurb on the sales pages, no qualified lab would ever use something like this for pathology or any serious purpose; this is more of a toy than a microscope. Celestron has their "Handheld Digital Pro Microscope" that's very similar in specs to yours, but retails for about US$ 150 - just for some comparison from a manufacturer that has a good reputation for imaging equipment (telescopes in their case). I don't think that it is broken, just that you have reached the limits of its magnification capability and if you were able to move it slightly closer or further away from the calibration you would get this in-focus. That it is out of focus indicates either that the stand is off by a bit (you definitely need a stand for that sort of magnification), or that the manufacturing of the microscope is slightly out. At 220x the engineering specs need to be pretty tight to get consistent focus. You won't get that sort of tolerance on a cheaper 'scope. This is definitely not spherical aberration, as that would manifest as distortion of the image at the edges - a bit like a fish-eye effect. There will be some aberration in the lens (almost impossible to make one without), but this is probably corrected by a combination of software (like in your phone camera) and cropping of the image to only the centre of the image. As you have brought it recently I would reach out to the supplier and see if you can get a replacement or a return/refund. If you have brought this for business use, get the company to fork out for a decent microscope brand - not only will they be more robust, they will give much better images and come with good technical support. Good lenses and microscopes are very expensive and you only consistently get good lenses from well known manufacturers (Zeiss, Olympus, Nikon, Leica are the big names). There are some cheaper brands (e.g. Konus, Celestron [these two mostly known for telescopes], Saxon, AmScope) that make some moderate quality microscopes for not too-high-a price (~$1,500) that make good basic microscopy starter packs. Second-hand microscopes are fairly common on re-selling sites such as eBay too, just make sure you get to see/use it before purchasing. Without knowing your use-case I can't make any recommendations on what sort of microscope might be useful for you if you were to get a replacement, but your "classic lab microscope" is known as anUpright or Compound microscope, used for looking at small things up-close withtransmitted lightgiving you a flat 2D image. You might be familiar withstereo-microscopes, which are commonly used for looking at large objects up-close in 3D, usually using reflected light. Stereo-microscopes are also often used for things like soldering electronics and manufacturing quality control in textiles.

Answer 1

The microscope in question appears to be a basic model with potential limitations in lens quality and manufacturing precision, likely more suitable for hobbyist use than professional applications.

Step-by-step explanation:

The provided information suggests that the microscope's image quality, especially at higher magnifications, may be compromised due to potential shortcomings in lens quality and manufacturing precision. The lack of information about the lens manufacturer, the absence of reviews on microscopy sites, and the microscope's resemblance to lower-priced models from reputable manufacturers allude to its basic nature. The observed differences in sharpness between images at various magnifications may indicate limitations in the microscope's design and construction.

While it may suffice for basic hobbyist use, it is not recommended for serious scientific or professional applications, such as pathology. Consideration of alternatives from well-known manufacturers known for imaging equipment, or reaching out to the supplier for a possible replacement or refund, is advisable for those seeking higher quality and reliability in microscopy.
