Telescope Kits

Simple telescope kits of lenses and mechanics for building afocal two-lens systems that transform a collimated beam into a collimated beam of different width, used as custom beam expanders or reducers. Two convex lenses give an inverted image, while a concave and a convex lens give an upright one. Kits are offered with UVFS or BK7 lenses, uncoated or AR coated for ranges such as 210-400 nm, 350-900 nm or 532-1064 nm.
