1 Using a 1200 Lines/mm grating measured near blaze wavelength of 400 nm.
2 Measured by comparing the peak throughput of a HeNe laser source at 632.8 nm to ±2 nm off peak at 0.5 nm
spectral bandwidth using 1200 Lines/mm grating blazed at 500 nm.
3 Exposure time measured from closed to open to closed shutter.
4 Using the mechanical shutter as a beam chopper will reduce the lifetime of the shutter and it is not commonly
used for this purpose.
