Edmund Optics has introduced its Techspec Nd:YAG Laser Line λ/20 UV Fused Silica Right Angle Prisms. These versatile prisms offer a combination of precision surface flatness and guaranteed laser damage threshold anti-reflective coatings. They are ideally suited for a wide variety of beam steering applications with minimal wavefront distortion. These λ/20 right angle prisms are available as both standard or custom products.
The new prisms provide precision λ/20 surface flatness and 20-10 surface quality. They are designed for transmission through the legs of the prism, exhibiting less than 0.25 per cent reflection for fibre and Nd:YAG applications. The prisms feature a ±15 arcsec angular tolerance, which ensures consistent alignment for volume integration.
Manufactured from a fused silica substrate, Techspec Nd:YAG Laser Line λ/20 UV Fused Silica Right Angle Prisms have an anti-reflective Nd:YAG coating with laser damage thresholds of 3J/cm2 at 266nm, 7.5J/cm2 at 355nm, 10J/cm2 at 532nm, and 15J/cm2 at 1,064nm for minimised reflection at common laser wavelengths. The prisms are available in sizes from 5-25mm.
