The most common type of achromat
lens, according to the company, is a doublet, a compound lens consisting of two elements cemented together.
Other features include 8x magnification, a two-element achromat
in the objective, Zeiss's scratch-resistant T* lens coating and an automatic brightness control that self-adjusts the red LED.
A new series of BE Plan Achromat
objectives have been designed especially for the E100 with excellent optical corrections and very flat (Plan) optical performance.
The LE-600 is a direct view HMD with no external box and 3 element Achromat
optics, providing a 32ae FOV at SVGA, suitable for situational awareness, portable computing, and remote viewing for medical, industrial, and military applications.
Tenders are invited for Fluorescent microscope with plan achromat
objectives with colour ccd cooled camera with software, computer , ups and laser printer.
However, observing the crater Muller on 2008 October 8 with my 100mm Borg Achromat
I did gain the impression of a darker streak running along and down the crater wall and aligned with the distinct crater chain beyond.
