More about part: Optical N-117M / Brunel microscope collector lens with frosted diffuser and filter holder | BestScope BS-2020 and Delta Optical Genetic Pro compatible (ID: 91023)

Description

Light collector lens with a frosted filter (diffuser) for microscopes based on the N-117M / DN-117M models. The lens is mounted in a plastic housing, which also serves as a filter holder.

Mechanically, this lens in its housing is located in the microscope base, underneath the condenser. It is screwed into the base (the housing is threaded), while the light source (halogen or LED) is located directly below this collector.

This is certainly not a complete list – many sellers give the microscopes they sell their own names (just like Delta Optical in Poland). The best way to check whether this microscope part fits your microscope is to compare the appearance of your microscope with the microscope from which this microscope part was removed ([[ LINK ]]).

The N-117M model has a binocular or trinocular head, while the DN-117M model has a built-in digital USB camera (hence the “D” at the beginning of the name, for “Digital”). However, the microscope body is identical – regardless of whether a halogen bulb or LED is used for illumination. Therefore, this collector lens is also the same in all these models.

This microscope part performs several functions:
- it collimates the light beam
- the built-in frosted glass diffuser provides uniform illumination, preventing discoloration in the area of the filament
- it also serves as the holder for round filters

The last photos in the gallery show the entire N-117M type microscope, with an arrow indicating which microscope part is being described and where it is located. This helps prevent any confusion when identifying the microscope part.
