70%: 30% beam splitter

It is used for beam separation and synthesis of optical instruments, synthesis of 3D pictures, color processing of AOI automatic optical detector, and light splitting of laser tube cap in optical communication band.

UV band: 250 ~ 400nm spectral, spectral ratio T: r = 50:50 (according to the needs of customers)

Visible light band: 400 ~ 700nm spectral, spectral ratio T: r = 50:50, t: r = 70:30 (according to customer requirements)

Near infrared band: 700 ~ 1700nm light splitting. Typical wavelengths include 850nm light splitting diaphragm and 1310 / 1550nm light splitting diaphragm (light splitting ratio T: r = 50:50, etc.)

Advantages: no ghosting, small PDL value, clear imaging, small spectral ratio error, and can be purchased in large and small batches.
