# Part manufacturer:
Optical

# Full manufacturer name:
Optical

# Belongs to category:
Revolvers (turrets)

# Description and specifications:
4-position nosepiece for microscope objectives with RMS thread.

This nosepiece fits many microscopes based on the N-117M / DN-117M models.

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 nosepiece 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 entire microscope body, and therefore the nosepiece as well, is identical in both models.
