Interference Filters

DIEN TECH provides high quality standard and custom-made narrow bandpass interference filters within the spectral range from 200 nm to 2300 nm.
Plano-Concave Lenses

Plano-concave lens is the most common item used for light projection and beam expansion. Coated with antireflective coatings, lenses are used in various optical systems, lasers and assemblies.
Super Achromatic Waveplates

Super Achromatic Waveplate can provides extremely flat phase delay in a large Wavelength broadband. The broadband of Quarter Waveplates are 325-1100nm or 600-2700nm, the Half Waveplates are 310-1100nm or 600-2700nm. The Super Achromatic Waveplate of standard adopt Glued strutures.We can customize phase retardation and wavelength according to customer’s requirment.
True Zero Order Waveplate

Single Plate True Zero-Order Waveplate has broad spectral bandwidth ,wide temperature bandwidth ,wide angle bandwidth,high damage threshold with standard wavelength: 1064，1310nm, 1550nm and thickness down to 0.028mm.
Low Order Waveplate

Low Order Waveplatesare much better than the multi-order wave-plates because of its thinnerthickness less than 0.5 mm). Better temperature(~36°C), Wavelength(~1.5 nm) and incident angle(~4.5°) bandwidth and high damage thresholdmake it widely used in common application. Also it is economical.
Zero-Order Waveplates

The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction.Zero order waveplate shows better performance than multiple order wavepalte.It has broad bandwidth and a lower sensitivity to temperature and wavelength changes.It should be considered for more critical applications.
