Supplier: Synrad, Inc.
Description: and collimates the beam diameter by 5x, reducing or eliminating damaging hot-spots and optics damage that can sometimes occur in harsh operating environments. Ruggedly crafted from a single block of aluminium and anodized for added corrosion resistance, BE beam expanders conveniently and easily mount
Supplier: CVI Laser Optics
Description: CVI Melles Griot stocks mounted prism pairs with aspect ratios from 2:1 to 6:1 for one-dimensional (anamorphic) expansion or reduction of any laser beam. A 1/4-20 threaded mounting hole is centered on the base. The input face of each prism is aligned to near Brewster's angle so an AR coating
Supplier: Ross Optical Industries
Description: These lenses have one flat surface and one concave surface. They have a negative focal length and are used to diverge incoming light, or to increase focal length in an existing optical system. They can be used in beam expanders and projection systems.
- Lens Type: Spherical Lens
- Lens Application: Infrared, Visible, Ultraviolet
- Focal Length: -1.57 inch
