This is a difficult kind of beam splitter in a cemented cube. The specification is: under angle of incidence (AOI)=55o, the reflectivity at 905 nm is no less than 85%, and in the visible range the average transmittance is 40+(-)2%

Design and preparation of multilayer optical coatings are investigated on laser crystal Nd:YVO4, YVO4, and frequency doubling crystal KTP substrate. Multilayer optical coatings are deposited on one surface of the crystals using th

For high precise laser systems like laser gyro, gravitational waves interferometers, the optical components which lie in the cavity or laser path need to control the total loss, scattering, reflection, absorption, and so on. Low l

A fiber-optic relative-humidity (RH) sensor composed of multilayer of porous dielectric films is proposed. The transducer deposited on fiber end-face is multilayer coating consisting of nano-porous TiO2 and SiO2 films, which forms

The preparation and characterization of in-plane polarized lead zirconate titanate (PZT) piezoelectric diaphragms for sensors and actuators applications are demonstrated in this letter. The single phase PZT films can be obtained o

Aiming at the crosstalk problem caused by small spectral intervals between fluorescent reagents in fourplex fluorescence quantitative polymerase chain reaction (PCR) detection analysis system, we calculate and analyse the effect o

In this letter, using mult-half-wave structure and some chosen films optimized method, the long-wave infrared (LWIR) narrow-band pass filter is investigated, meanwhile the opposite of the substrate coated with long-wavelength pass
