Presented as highest rated relay in this pin configuration for AC, relays are available with ratings such as 12, 24, 48, 110, 120, 220, 240 and 277 VAC. (DC coils are also available.)

Optical Process Reproduces Complex Surfaces

May 27, 2008 5:19 am | Comments

Providing a means for engineers to create high-performance optics at volume quantities, a novel replication process transfers the profile of a precision optical surface from a master, creating an exact duplicate on a variety of substrates. The process can produce a wide range of both ruled and holographic diffraction gratings, reflective and transmission holographic optical elements, and dual wavelength gratings, as well plano and conic sections. Diffraction gratings are produced in sizes up to 110mm x 110mm with groove densities from 40 g/mm to 3600 g/mm, with available wavelengths from
