Changchun Jinlong Optoelectronics is a professional manufacturer of precision optical components and optical lenses. The company is located in Changchun, Jilin Province, the optical base of New China. Since its establishment in 2000, the company has actively developed and innovated, growing into a modern optical enterprise integrating design, production, and sales.

Main products include four major series: precision optical lenses, optical components, coating products, and optical design services.

Optical Lens Series
Optical lenses mainly include various zoom lenses, collimating and beam-expanding lenses, and telecentric lenses. They are primarily used in photoelectric instruments, medical instruments, financial machinery, teaching instruments, semiconductors, optical communications, laser applications, and other fields.

Optical Components Series
Changchun Jinlong Optoelectronics is a leading standard optical component manufacturer in China. Main products include various spherical lenses, cylindrical lenses, optical windows, optical prisms, mirrors, and filters made from optical glass, optical crystals, and fused quartz. The company currently maintains an inventory of over a thousand types and tens of thousands of pieces in stock.

Optical Coating Series
Coating products mainly include anti-reflection coatings (UV, visible, near-mid infrared), dielectric high-reflection coatings (single-point, broadband), metal high-reflection coatings (gold, silver, aluminum, chromium), beam-splitting coatings (dichroic, half-reflection half-transmission, polarizing beam splitters), filters (narrowband 10nm, bandpass 40nm, long-pass/short-pass), and various other high-difficulty, high-precision optical coatings.

Optical Design Services
Changchun Jinlong Optoelectronics Technology Co., Ltd. has an optical design team capable of providing optical system design and custom industrial lens services to meet a wide range of customer requirements.

The company possesses design and production teams for optics, mechanics, and electronics. Utilizing domestic and international optical processing equipment, coating equipment, mechanical processing equipment, and high-precision testing equipment, the company processes and manufactures various optoelectronic products for clients at home and abroad.
