Procurement Guidance

Frequently Asked Technical Questions

Direct technical insights to assist procurement managers and optical design engineers.

What are the key technical criteria when choosing between JGS1, JGS2, and JGS3 quartz?

Selection depends primarily on operational wavelength and heat sensitivity. JGS1 is synthetic fused silica offering peak optical transmission in the deep ultraviolet band (down to 185 nm) with zero bubbles, ideal for excimer lasers and optical windows. JGS2 is natural fused quartz engineered for visible spectrum optics and high-temperature thermal tubes (up to 1,100°C continuous). JGS3 features near-zero hydroxyl (OH < 5 ppm) content, preventing strong absorption bands at 2,730 nm and ensuring pristine infrared transparency up to 3,500 nm.

How does BY Photonics prevent micro-cracking during CNC ultrasonic grinding of brittle quartz?

Our CNC machining centers utilize high-frequency ultrasonic oscillation coupled with specialized diamond-plated tooling and sub-zero liquid cooling. This drastically lowers cutting force, eliminating subsurface micro-fissures. After machining, parts undergo controlled thermal annealing at 1,120°C to release residual mechanical stresses before final double-side optical polishing.

What tolerances can your wholesale manufacturing lines routinely achieve?

For flat components (windows, substrates), we consistently hold dimensional tolerances of ±0.01 mm, surface flatness up to λ/10 @ 632.8 nm, parallelism < 10 arcseconds, and surface quality down to 10-5 or 20-10 Scratch-Dig. For precision redrawn capillary tubing and multi-bore tubes, inner and outer diameter tolerances can be locked to ±0.005 mm.

Can you produce custom laser pump cavity reflectors from PTFE and doped glass?

Yes. We precision-machine diffuse reflectors from spectralon-grade sintering PTFE with > 99% diffuse reflectance across 400–1,500 nm. Concurrently, we manufacture custom samarium-doped (Sm³⁺) glass flow tubes and yellow cut-off quartz sleeves that filter out harmful UV and suppress 1,064 nm parasitic self-oscillation in high-power Nd:YAG laser systems.

What is the standard procedure for quotation, sample validation, and volume export?

Clients supply 2D engineering drawings (DWG/DXF/PDF) or 3D CAD files (STEP/IGES) specifying material grade, surface finish, and quantities. Our engineering team provides a full DFM evaluation within 24 hours. Prototypes are fabricated and dispatched via express air courier within 7 to 10 days. Repeat wholesale volumes benefit from dedicated production lines and inventory buffer warehousing.
