Ocular Micrometer & Stage Micrometer

I was surprised to get both the rectangular and circular targets. I have not used them yet but the quality looks good

For the price, this is a fantastic product. I had a hard time finding a reticle for my microscope, so I was pleased to finally find this one and that it came with a calibration slide. It was a bit of a gamble as the dimensions aren't listed anywhere (at the time of writing) and as you can see in the picture, it is a bit small for my WF 10x DIN/18mm eyepiece, but it does the job. Besides the dimensions not being listed, my only complaint is that the reticle is somewhat pitted. My eyepiece is clear without it, so the black specks in the picture are on the reticle (even after cleaning). Overall, I really recommend it! Especially if you can't afford a name brand one.

I was expecting to have to spend £40-80 for a good 10 micron stage micrometer however this one has proved me wrong. It provides the same level of accuracy as more expensive models with the marks not being too wide at 400x magnification. The occular was too small for my eyepiece but is of good quality also.

Purtroppo mancano delle indicazioni su come vanno usati!. Manca poi il diametro della lente di calibrazione. Spesa inutile.

Si pero una pregunta existen de diferentes medidas porque a un microscopio viejito carl zeiss le quedó muy bien pero a uno nuevo no le quedó chico

I bought this for my Swift SW380B microscope which was also purchased here on Amazon, but I needed to make a 3D printed adapter to fit the ocular insert into the 10x eyepiece, which was 20mm ID and seems to have no way to secure an insert like this. One reviewer noted that the calibration slide did not match the description and was actually 0.1mm/div, but the slide I received is in fact 0.01mm/div as per the description. The lines are sharp and clearly defined, and they appear to be evenly spaced. When viewed at 100x and 1000x magnification, both scales seem to be properly aligned such that one division of the ocular is 10 micrometers at 100x and 1 micrometer at 1000x. I am unable to clearly discern the alignment at 40x, but another slide with 0.1mm/div should help with that.

Un indispensable pour calibrer le microscope. Efficace et bon marché

Achtung! Nicht alle Mikroskopokulare sind geeignet für den Einbau. Vorher sollte überprüft werden, ob sie aufzuschrauben sind und ob es einen Ablagegrat in Brennweitenentfernung gibt, der den kreisrunden Einsatz in Position gerade hält.
