# Belongs to category:
Eyepieces

# Description and specifications:
LOMO compensating projection microscope eyepiece with 3x magnification

Manufacturer: Lomo (ЛОМО)
Marking on the eyepiece: AK-3 K3xПР
Magnification: 3x
Kind: PR (ПР) - projection eyepiece for photomicrography
Type: K - compensating eyepiece
Mounting diameter: 23.2 mm

Projection eyepieces are special microscope eyepieces used to project the microscopic image onto the sensor of a camera. Many microscope photo tubes and trinocular heads have a seat for a projection eyepiece.

The "compatibility" section lists the microscope models this eyepiece can be used with, but only LOMO microscopes are listed there, as examples, and that list is of course not complete. This projection eyepiece can be used with any microscope of any manufacturer, as long as it has a tube or another seat for an eyepiece of 23.2 mm diameter.

# Examples of use
- if your microscope has a photo tube or a trinocular head with a 23.2 mm seat and you want to take photographs using a projection eyepiece
- if you already have such an eyepiece, but it is damaged, scratched or has fungus on the lenses
- if you want to keep a projection eyepiece as a spare
- if you want to use this eyepiece in a microscope of another manufacturer fitted with a 23.2 mm seat
- if you need a compensating eyepiece for photomicrography, because your objectives require correction of chromatic aberration
- if you are trying out projection eyepieces of different magnifications to find the best one for your microscope and camera combination - and you want to test this one
- if you have neither a photo tube nor a trinocular head, but want to use the eyepiece for photomicrography through the eyepiece tube
