The filter

The filter ( multi-band light filter ) products are BP360nm filter, 415450490510nm, 530555570590610 blue chip, attenuation. Multi-band color wheel filter ... .. Using special bonding technology, cut-off filter high, can guarantee the purity of light source, our company provided a wide band light source commonly used filter ( can separate order / matching order ):

Product features: can excite fluorescence, eliminate the background interference, enhanced traces contrast.

Application fields:

Traces, fingerprint, forensic, criminal photography, drug testing

Fingerprint products, product, product, traces of criminal forensic products, drugs and infectious disease test reagent products and criminal investigation technology need other products

System structure: light source, filter system, output control system, display and processing system

In the past the light source used mainly in ultraviolet light, laser light, blue light, spot perambulate lamp, the light source while the high strength, good monochromaticity, but usually they are bulky, energy conversion rate is low, its limited output wavelength and output of high-intensity white light, so that it cannot well meet the actual work need to. In order to give full play to all kinds of examination of material evidence in optical inspection methods, to adapt to the science and technology development, domestic and foreign criminal technology development department of the multi-band light source to replace the light source. A variety of optical inspection method is continuously applied to criminal technical field, in particular the practice of field survey and examination of material evidence plays a more and more important role.

Multi wavelength light source is composed of a plurality of groups of the special design of the filter, the light source emits white light into different wavelength, and then through the light guide light output, this optical system is known as the multi-band light source. High quality band pass interference filter, by properly combining to select the output light. At present, large multi-band light source can be equipped with more than a dozen filter. Performance is more perfect, the band range ( 6 - -25 band, 280 -- 1100nm ). Can excite fluorescence, eliminate the background interference, enhanced traces contrast.

The application of filter lens: 3 color temperature orange

In fluorescence mode:

Yellow glasses in 365, 415nm enough protection

Orange glasses provided in the excitation band 365, 415, 450, 470, 530nm protection

Red glasses is provided in the 365, 505, 530 band filter and protection
