Holmarc beam expanders provide accurate, unobstructed and achromatic expansion of any collimated input source and are easy to use.
Holmarc’s variable beam expanders are based on Galilean design. This 5-element diffraction limited design allows continuous beam expansion within the specified range.
Condenser is a combination of lenses with short focal lengths used for concentrating a light source onto a small area. The lenses are mounted in a black anodized aluminium casing.
Our Fiber collimators/focusers are designed for laser applications which require pure Gaussian beam. Holmarc Fiber Collimators are available from 5mm to 40mm aperture size.
