Melles Griot 01 LAO 366, 07 LHF 029  Lens Mount for 80mm Optics with 1000mm FL Achromat

This 1000mm focal length cemented achromat is mounted in a type 07 LHF 029 lens holder. The mount has been slightly modified by the addition of a small groove about the outer periphery, probably to aid in holding the element within a lens chuck. The two threaded bores are not damaged.

The lens itself exhibits very pale Newton rings, but the cement layer does not have any voids it may be some sort of coating artifact. The optic performs perfectly and is free of any surface blemishes. The Newton rings were far too pale to be visible in the photos and conditions have to be optimal in order to detect them. Optic diameter is 80mm. Lens is retained within the cell by a threaded ring and it may be easily removed. Melles Griot part number for the objective is 01 LAO 366.
