Frequently Asked Questions (FAQ)

Q1: What materials and spectral bands does this quartz transparent plate support?

A: We offer three main materials: JGS1 (ultraviolet grade), JGS2 (general transparency grade), and JGS3 (infrared grade). JGS1 is suitable for the deep ultraviolet to near-infrared spectrum (185 nm–2100 nm), JGS2 is suitable for the standard visible light spectrum, and JGS3 offers excellent light transmission in the infrared spectrum, comprehensively meeting all types of spectral analysis needs.

Q2: In addition to standard sizes, do you support custom non-standard shapes?

A: Absolutely. We have flexible secondary processing capabilities. In addition to standard circular and square sizes ranging from 8 to 500 mm, we can also perform custom cutting, precision drilling, slotting, edge grinding, and chamfering according to drawings. Thicknesses range from 0.1 mm to 50 mm to meet various special assembly requirements.

Q3: What standards can the product’s surface precision and finish meet?

A: We offer a variety of surface quality options ranging from standard to high-precision grades. Standard-grade finishes can reach 60/40, while high-precision grades can reach 20/10 or even better; surface profile accuracy (PV value) can be customized to λ/10 or λ/20 as required, and parallelism can be controlled within 1 arcminute to ensure the imaging quality of optical systems.

Q4: Can quartz plates be coated?

A: Yes. We offer a variety of optical coating services, including single- or double-sided anti-reflective (AR) coatings, wavelength-specific anti-reflective coatings (e.g., 1064 nm, 532 nm), broadband anti-reflective coatings, and hydrophobic and water-repellent coatings, to minimize reflection loss and maximize light transmittance.
