OECCDD02-700 is a 700nm short pass dichroic filter from Optosupply. This filter is designed for use in biological research and other applications where narrow-band illumination is necessary. It has an industry-leading optical performance, and is made with high-quality, hard-coated, low-reflection optical elements that maximize transmission and absorption. The filter features a wide passband of approximately 400nm, a steep cut-off on the short-pass side, and an incredibly high transmission of more than 90%. Additionally, the OECCDD02-700 is designed specifically for use in microscopy, imaging, and optical spectroscopy applications.
