650nm Bandpass Filter for Laser ccd barcode scanner 650+/-15nm Narrow Bandpass Filter, or said 650nm Interference Filter, compared to 650+/-25nm filters, it can reduce more unexpected light for some special sensitive sensor requirement, to get the clear signal response. The higher transmission at T>=90% allow this filter available to be combined with other existed filter and still keep the transmission no less than 85 650+/-20nm Narrow Bandpass Filter, or said 650nm Laser Scanner Filter, is a new developed spectrum with higher transmission at T>95% @ 650+/-5nm area, perfectly used for laser equipments, such as laser scanners. The noise signals have been deeply blocked, with Tave<0.2% @ other visible light area. 650+/-25nm bandpass filter, based on the common applications, is usually called Laser Scanner Filter, which is commonly used with from 639nm to 660nm laser light sources. It only transmit the small bandwidth of red laser light in the range of 650+/-25nm while block or reflect all the other spectrums. The blocking rate is not very strict for these types of application, because most laser scanner application just mainly required the T>90% @ centre wavelength point, without considering the noise in image forming system.. This type of filter is usually used for laser semiconductor use, such as laser bar code scanner, laser measuring equipment, 647nm laser light source device, NIR range finder, fingerprint identification system etc. Actual Measurement Cure Applications Fluorescence Microscooy, UV-VIS irradiation,Camera Imaging, Stage Lighting, Architectural Lighting etc FAQ: Who We Are Founded in 2010, Changchun Ruiqi Optoelectronics is located in Changchun, Jilin Province, the optical base of China Products Show Factory Show http://www.ruiqi-optics.com650nm Laser Filter for Barcode, 650nm Band-pass Filter for Fluorescence Analyzer, 650nm Short Pass Filter,
