Reduce Beam Wander With Compactly Designed 1064nm 2X-8X Gemma® Variable Beam Expander

BARRINGTON, N.J., Jan. 31, 2023 (GLOBE NEWSWIRE) -- Edmund Optics®, a leading global manufacturer and supplier of optical components, has expanded its extensive inventory by releasing the 1064nm 2X-8X Gemma® Variable Beam Expander. Featuring a high LIDT and fixed housing length, these beam expanders are designed for high-power laser applications with strict spatial requirements. To minimize beam wander, an internal translation and focusing mechanism is utilized to allow for magnification adjustments without rotating the lenses. Their adjustable 2X-8X expansion power allows for easy prototyping to determine suitable system magnification.

Designed with Gaussian beams in mind, the 1064nm 2X-8X Gemma® Variable Beam Expander has no ghost foci and features non-rotating lenses in a Galilean configuration to provide a high degree of pointing accuracy while also maintaining a compact housing length of 158mm. An anti-reflective coating is utilized to ensure superior transmission while withstanding high-power laser pulses of up to 10 J/cm2 at 1064nm, 10ns, 20Hz. The Gemma® Variable Beam expander is currently in stock and available for immediate delivery.
