SEIWA LWD objectives for NUV range

 Posted on July 18, 2011

 

SEIWA Long Working Distance Plan Apochromat objectives for NUV range.
Brightfield super-long working distance objective lens. The focal plane is corrected for both Bright Field and Near UV (355nm), meaning both wavelengths will be in focus.
System is optimized for high transmission at 355nm, such that a microscope fitted with a YAG laser can be used for repair of semiconductor and LCD circuits.
Objectives listed here come without cover glass correction. But special versions with 1 mm cover glass correction are available, mainly intended for work on LCD panels.

Adapter allows installation on Mitutoyo style nosepiecesObjective uses RMS (20.2 mm x 36TPI) mounting thread. On request we will supply an adapter free of charge to make the objective compatible with Mitutoyo style nosepieces using 26 mm x 36 TPI threading, see image at left.
We use this adapter since several years on a range of NIR objectives.

Please contact us with any questions.
