Lens no. 718805 - unknown purpose / M27 thread (From the condenser? From the objective? Tube lens?)	Description of this part for the microscope. The lens is convex on one side. The metal housing has an M27 thread on one end and keyholes on the other. It could be the tube lens, maybe part of the condenser, ... maybe the rear of the lens, maybe the lower element from the head, or something else entirely. I don't know the manufacturer either, but if someone recognizes it from the font or number, please contact me :) Names, descriptions, terms, and search contexts under which this part is searched.

1165 - Thumbnail photo showing this microscope part. Optical N-117M / Brunel microscope collector lens with frosted diffuser and filter holder \| BestScope BS-2020 and Delta Optical Genetic Pro compatible - thumbnail [ 91023 ] video	SERMIK_ID number under which this microscope part is placed in the database. 91023	Optical N-117M / Brunel microscope collector lens with frosted diffuser and filter holder \| BestScope BS-2020 and Delta Optical Genetic Pro compatible	The name of this microscope part. Optical N-117M / Brunel microscope collector lens with frosted diffuser and filter holder \| BestScope BS-2020 and Delta Optical Genetic Pro compatible	Description of this part for the microscope. 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. The N-117M / DN-117M microscope is a fairly good laboratory microscope manufactured at the Chinese NYO factory and sold worldwide under various names. These microscopes are known and sold, among others, as: - Delta Optical Genetic Pro (mainly in Poland) - AmScope B340 / T340 (mainly in the USA and the rest of the world through Amazon) - Labtron LEM-C10 / C11 / C12 (mainly in the UK) - Sigeta MB-207 (mainly in Ukraine) - Boeco Germany BM-117 (mainly in Germany) - BestScope BS-2020 (mainly in the USA, shipped worldwide) - Brunel N117M (mainly in the UK) - Apex N-117M (mainly in the UK) - Surgifield SM-DN-117M (mainly in Nigeria and West Africa) - Eurotech DN-117M (mainly in Peru) - Biocare DN-117M (mainly in Peru) - Viresa N-117M (mainly in Mexico) - Eurolab DN-117M - Nexcope N-117M - Novel N-117M 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 (https://www.microscopeparts.eu/microscope/optical-n-117m-388). 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. Names, descriptions, terms, and search contexts under which this part is searched.

Optical N-117M / Brunel microscope intermediate Telan lens \| Nexcope and Delta Optical Genetic Pro compatible	Description of this part for the microscope. Telan intermediate lens for the stand of microscopes based on the N-117M / DN-117M models. This lens has a metal housing with a thread at the bottom. ... Mechanically, it is located inside the microscope head mounting bracket and is screwed into the objective nosepiece from above, so it also serves as the mounting for the objective nosepiece. The N-117M / DN-117M microscope is a fairly good laboratory microscope manufactured at the Chinese NYO factory and sold worldwide under various names. These microscopes are known and sold, among others, as: - Delta Optical Genetic Pro (mainly in Poland) - AmScope B340 / T340 (mainly in the USA and the rest of the world through Amazon) - Labtron LEM-C10 / C11 / C12 (mainly in the UK) - Sigeta MB-207 (mainly in Ukraine) - Boeco Germany BM-117 (mainly in Germany) - BestScope BS-2020 (mainly in the USA, shipped worldwide) - Brunel N117M (mainly in the UK) - Apex N-117M (mainly in the UK) - Surgifield SM-DN-117M (mainly in Nigeria and West Africa) - Eurotech DN-117M (mainly in Peru) - Biocare DN-117M (mainly in Peru) - Viresa N-117M (mainly in Mexico) - Eurolab DN-117M - Nexcope N-117M - Novel N-117M 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 (https://www.microscopeparts.eu/microscope/optical-n-117m-388). 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”) – but the stand is shared by both models, so this Telan lens fits both models. Microscopes based on the N-117M model have an objective nosepiece tilted inward, and in my opinion this is why a Telan lens is required even though this is a microscope using optics corrected for a 160 mm tube length. Other names are sometimes used for the Telan lens installed in the microscope, for example: - nosepiece lens - intermediate lens - tube lens (although this is an incorrect term, because a really “Tube lens” has a different function) The last photo in the gallery shows the stand of an N-117M type microscope, with an arrow indicating which microscope part is being described and where it is located.
