Quick Overview

Our research range of high-quality replica reflection gratings includes both ruled and holographic types. Generally ruled gratings have higher efficiency, while holographics have lower stray-light levels and are available in closer rulings. For the UV, however, blazed holographics are available with a similar profile and efficiency to ruled type..

Description

Our research range of high-quality replica reflection gratings includes both ruled and holographic types. Generally ruled gratings have higher efficiency, while holographics have lower stray-light levels and are available in closer rulings. For the UV, however, blazed holographics are available with a similar profile and efficiency to ruled types. Efficiency curves are available on request.
The commercial range are inexpensive transmission replicas mounted between glass plates and are suitable for simple demonstrations, etc.
