Optical Element Manufacturers

Our 2-4w Diode-pumped Pulsed solid-state Laser have been recognized by our customers with advanced production technology and good quality.

Our MgO Single Crystal Substrate products are your best choice! MgO single crystal substrate from Coupletech is an excellent single crystal substrate which can be widely used in many thin film technology fields. Since the MgO single crystal has a small dielectric constant and loss in the microwave band, and large area of the substrate can be obtained, it is one of the most important industrial high temperature superconducting film single crystal substrate, suitable for ferromagnetism, photoelectron and high temperature superconducting thin films, etc.

We have many years of experience in the production of Short-wave Pass Filters. Short-wave pass filters are specifically designed to transmit wave lenghts shorter than the cut-off wavelength while rejecting longer wavelengths. Short pass filters can be used in many applications and can be used with long pass filters for custom band pass filtering. We offer standard short-wave pass filters, which consists of 650nm Short pass Filters, 532nm Short pass Filters, 800nm Short pass Filters, and so on, AOI: 0°.

We are experts in the field of Long-wave Pass Filters. Long-wave pass filters are specifically designed to transmit longer wave lengths than the cut-on wave length while rejecting shorter wave lengths using either absorption or reflection. Long pass filters are uesful in a variety of applications and can be used with short pass filters for custom band pass filtering. We offer several types of long-wave pass filters as well as long wave pass filter sets.

Our Absorptive or Reflective Neutral Density Filter products are popular in the market. Neutral Density Filter belongs to Polarization Optics, as a kind of core Optical Elements of Laser Components, is including Neutral Density Filter Absorptive and Neutral Density Filter Reflective. Neutral Density Filter are used to attenuate light over a wide spectral range by coating a durable metallic film. The Polarizing Filter can be used with white light as well as with lasers. It is a kind of Optical Filters that reduces or modifies the intensity of all wavelengths, or colors, of light equally, giving no changes in hue of color rendition.

Our Narrow Band Filter With Different Wavelengths is well received in the market. Narrow band filter is a kind of Optical Filters, which can separate out the monochromatic light of a band, allows optical signal through specific waveband, nevertheless the light signals from both sides of the waveband are blocked. The band of narrow bandpass filter is relatively narrow, it is generally less than 5% of the central wavelength.
