Legal notices : coherent.com/legal sales@coherent.com www.coherent.com Extended operational range: The grating may operate over broader wavelength range provided that suitable anti- reflective coating and angle of incidence is used. The plot below shows simulated performance* over extended range assuming fixed input angle (designed Littrow angle of 58°), not accounting for AR coating losses. Optimal input angle for each wavelength is shown on the right. The single polarization optimized transmission grating has 1600 lines/mm and designed to operate near 1060 nm central wavelength at 58° angle of incidence (AOI). Extended wavelength range performance and angular sensitivity information is provided below.
