IŽam planning to make a Kalosat aquilent lens for my self.
For this I want to order a fused silica meniscus lens.
Maybe some one other is interesting to get one of this lenses.
The meniscus lenses are available in Ű 2" (50.8mm) and focus length of 100mm, 150mm, 200mm, 250mm, 300mm, 500mm and 1000mm
Transmission is 185->2000nm
Prices for the lens element is around 400 Euros ± a little bit.
Further it needs a housing and a barrel with an aperture or a shutter, size II or III or maybe a Compound 3
Endprice will be much lower than an original lens but with the same optical results.
The lenses are available with special UV coating as well, makes the elements a little bit more expensive but has a few advantages.
Transmission is 285->1000nm
