Supplier Information
Changchun Sandi Optoelectronics Co., Ltd. was established in 2013, located in Changchun optical base. We are a comprehensive optical company capable of processing optical glass, coating, optical assembly and optical design. Sunday Optics mainly produces spherical lenses, aspherical lenses, cylindrical lenses, prisms, high-precision windows, filters, mirrors, coatings, laser lenses. The minimum lens size can be 0.3mm, and the prism 90-degree angle tolerance can be 2 arc seconds. We focus on high-precision optics, with surface roughness guaranteed to 0.1 nm. Our products are used in endoscope probes (0.3mm micro-lenses), satellite remote sensing payloads (300mm large-format windows), industrial ultrafast lasers (1064nm high-damage mirrors sustaining 15 J/cm²), and custom infrared aspheres replacing three-element spherical stacks for 60% size/weight reduction.
