Transmission gratings provide a straightforward and reliable way to disperse light in optical systems. Incoming light passes through the grating and is separated into its component wavelengths at a fixed output angle, making them ideal for fixed‑grating setups such as spectrometers and Optical Coherence Tomography (OCT). Their simple design also makes them more tolerant of minor alignment errors, offering an easy‑to‑integrate solution for a wide range of optical builds.
Key Features:
- UV and visible options
- 12.7mm and 25mm square formats
- Different groove angles available for optimised outputs
- Fixed output angle for stable wavelength separation
