Film Reticles with Micrometer Scale
Film Reticles with Micrometer Scale
HE1472290
Product code: HE1472290
Product Description
Plastic film reticle strips which consist of 5 eyepiece micrometer scales on each strip. 2 strips per pack including a total of 10 micrometer scales. They can be cut out to fit the size of any microscope with an eyepiece which measures 16-24mm. A cost effective alternative to buying microscope eyepieces with pre-fitted micrometers.
- Micrometer Scale: 10mm length with 100 divisions of 0.1mm
- Overall size 150mm x 30mm x 0.18mm thick
- Guide circles of 16mm, 19mm, 21mm and 24mm around each scale image for cutting.
How to Size a Reticle:
- Remove the eyepiece from your microscope and look at the bottom (open) end. There should be a threaded ring or plastic insert that is used to secure the reticle in place.
- If your eyepiece has a threaded ring then you need to measure the diameter of the eyepiece where the threaded ring is fitted (i.e. across the internal thread of the eyepiece).
- If your eyepiece has a plastic insert, then there should be a small recess (where the reticle sits) in the top of it and you should measure the width of that.
- The reticle actually fits at the optical plane in the eyepiece so that its image, and that of the specimen are both in focus.
- To check that you have located this plane it is easiest just to look through the eyepiece and insert a pencil up the open end until the point is in sharp focus - that is the position on the optical plane where the reticle is fitted. There should be a flange on the inside wall of the eyepiece to position the reticle up against.
