I know a lot of you out there are very knowledgable with respect to scientific optics.
This equipment is unidentifiable for me. It consists of three small OTA's of excellent quality and coated optics. The focal length is about 300mm. The kit also consists of an electrically sensitve meter that measures light intensity or through-put.
There is also a large plano-concave lens that measures 4"X6". Mounted to the inside of the two longer ota's is a small dark rectangle in the centre of the objective in the shape of the plano-concave lens.
Does anyone have a clue as to it's purpose or experimental value??
Thanks for all your help. My curiosity is worse than that of a cat
