Aberration-corrected concave imaging holographic gratings are the key elements in the design of outstanding, high-performance optical benches, spectrometers and monochromators for critical applications that require high-throughput and best optical purity for applications such as Fluorescence, Absorbance or light source tuning and wavelength selection.
The concave grating does it all: Both the dispersion & diffraction of the light, and the imaging & focusing onto the detector, without the need for additional optics. The simple design guarantees a robust assembly between input, grating and detector, with superb thermal stability, essential for devices used in industrial environments.
Careful design of the gratings at time of conception, precise holographic recording of the master and controlled replication processes in pristine laboratory environment guarantee an optical component that will deliver the best signal purity at the highest throughput possible, consistently, grating after grating, years after years.
Aberration-corrected concave gratings for monochromators are designed to work as scanning devices, between a fixed input and a fixed output. They are used in single and dual-monochromator layouts for scanning of the Excitation and Emission signals in a Fluorescence instrument, or to scan a specific wavelength in an Absorbance setup, or to select a specific band of light when matched to a broadband light source.
