Frequently Asked Questions

Type IV aberration corrected flat field and imaging gratings are produced with grooves that are neither equispaced nor parallel, and are computer optimized to form near-perfect images of the entrance slit on the detector plane. They also have a large optical numerical aperture and correction from aberrations, which makes them better than traditional Type I Rowland circle concave gratings.

The Type IV aberration corrected flat field and imaging grating provides much better light collection efficiency and signal to noise ratio than traditional Type I Rowland circle concave gratings due to their large optical numerical aperture and correction from aberrations.

When an area detector such as a CCD is utilized, it is often possible to focus multiple sources onto the entrance slit and independently evaluate the spectrum from each source.

It is designed to focus a spectrum onto a plane surface, making it ideal for use with linear or 2-D array detectors.
