Rhomboid Prism, Prism www.simtrum.com

Rhomboid prism can displace incoming light beam without a change in its image orientation. The incoming light beam undergoes total internal reflection by two 45° faces of the rhomboid side surface before exiting from the surface. Hence, allowing a lateral displacement to be performed. To achieve a higher transmission rate, the use of anti-reflective coating on the input and output faces is required. Rhomboid prism is typically used in stereoscopic system and periscope system.


Simtrum can provide angle tolerance<5 arc seconds, total beam deviation <30 arc seconds.BK7 is the most common optical glass used in high-quality optical components as it is a hard glass that can withstand a variety of physical and chemical exposure. Relatively scratch and chemical resistant, it has a low bubble and inclusion content, therefore making it an ideal choice for precision lenses. It is the ideal choice for general purpose visual and NIR applications as it has excellent transmission.
