L1 Dual-Combo Set
Filter stacking: broadband and narrowband coordination brings new possibilities to astrophotography. The set contains two filters, L-Quad Enhance and L-Para. L-Quad Enhance is a four-channel broadband filter balancing color and light-pollution suppression for continuous-spectrum RGB targets, nebulae, galaxies, and star clusters. It maximizes RGB color balance for broadband objects while improving contrast and detail for more distinct, dimensional images. L-Para is a dual-channel 10 nm narrowband filter with OIII and Ha transmission above 85% at F2 and higher focal ratios. Excellent contrast and halo suppression suit conventional and fast optical systems. It captures Ha and OIII signals to increase contrast and enrich their image detail.

Optical-glass neutral-density filter Optical Filters Uni-lens
Dimensional Tolerance: ±0.5 mm Surface Quality: 80-50 or higher Surface Figure: 4~6λ or better
Neutral-density filters make photographic exposure easy to control. By blocking light from reaching the camera sensor, they allow the camera to maintain a larger aperture for longer.

Machine-vision bandpass filter Optical Filters Uni-lens
Coating: Antireflection coating Surface Quality: 40/20 Guaranteed peak transmission: >90%
A bandpass filter passes frequencies within a specified range and rejects or attenuates frequencies outside it, selectively transmitting part of the spectrum while rejecting all other wavelengths.

Longpass filter Optical Filters Uni-lens
Filter Type [LP Series]: Optical interference or colored-glass filter
Long-pass filters serve gas monitoring, temperature sensing, other sensing, thermal imaging, and motion detection. They block shorter wavelengths and transmit longer wavelengths. Blocking can result from reflection, absorption, or both. An antireflection coating on the second surface can improve passband transmission.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
