Import Dielectric Hr Mirrors — Buy in Bulk from Supplier in China

Changchun Yutai Optics Co., Ltd. in China manufactures dielectric high‑reflectivity (HR) mirrors for precision optical applications. The mirrors are available with substrates of optical glass, white glass, quartz or silicon. Surface quality is specified as 20‑10 and the surface figure meets λ/10 at 633 nm. The clear aperture covers the central 90 % of the diameter, with a bevel of 0.25 mm cut at 45°.

Dielectric coatings on these substrates are designed for three standard laser lines - 480 nm, 546.1 nm and 643.8 nm - and typical reflectivity exceeds 99.5 % at each line. Industry practice tolerates a diameter variation of - 0.00 to - 0.15 mm and a thickness tolerance of ±0.1 mm, which matches the listed values. The λ/10 figure and 20‑10 surface quality correspond to the ISO 10110‑6 classification for high‑precision mirrors. Such specifications are common for components used in laser resonators, spectroscopy and telecommunications equipment.

OEM manufacturers and research laboratories often source these mirrors for wavelength‑specific reflection and low scatter performance. Changchun Yutai lists no public MOQ, price or lead‑time, so interested buyers should request a formal quotation to confirm trade terms. The supplier’s harbour verification tier indicates that basic company information has been validated, although the current response rate is zero, so follow‑up communication may require multiple attempts.

Changchun Yutai Optics Co., Ltd. is located in Changchun, Jilin province, China. The company is classified in the harbour verification tier on the platform, which confirms the existence of the legal entity and basic business details. Its public profile shows a response rate of 0 % and no recorded average response time, indicating that inquiries may not be promptly answered.

The firm specialises in producing dielectric high‑reflectivity mirrors and offers substrates of optical glass, white glass, quartz and silicon as indicated in the product listing. No additional certifications, capacity figures or client references are provided in the available data, so buyers should obtain any required documentation directly from the supplier.
