JGS1, JGS2 and JGS3 are fused silica materials with excellent transmittance in the ultraviolet, visible and infrared bands, which are widely used in optics, lasers, semiconductors and high-precision detection equipment. However, different application scenarios have extremely strict requirements for the cutting accuracy, dimensional tolerances, edge quality, and surface shape of quartz plates.

Frequently Asked Questions (FAQ)

Q1: What are the main differences between JGS1, JGS2, and JGS3?  

A: JGS1 is deep ultraviolet quartz with a transmission range of 185-2500nm and no bubbles; JGS2 is ultraviolet visible quartz with a transmission range of 220-2500nm, allowing for a small amount of tiny bubbles; JGS3 is infrared quartz with a transmission range of 260-3500nm, suitable for near-infrared applications. The three have similar high temperature resistance and chemical stability, but different spectral characteristics.

Q2: What are the minimum thickness and maximum size that you can cut?  

A: The minimum thickness can reach 0.5mm, and the maximum unilateral size can reach 600mm. It supports complex structures such as irregular cutting, step grooves, and openings, with tolerances controlled within ± 0.05mm.

Q3: How to handle the edges after cutting? Can microcracks be avoided?  

A: Adopting inner circle cutting and laser cutting processes, combined with annealing treatment. We can provide edge grinding, chamfering, and polishing to effectively eliminate microcracks and improve thermal shock resistance.

Q4: Does it support small batch sampling?  

A: Support. The minimum order quantity is 1 piece. After providing drawings for confirmation, a sample will be made and the sample will be verified before mass production.

What core user needs can be addressed?

-Resolve spectral matching issue: Based on your working wavelength, accurately recommend JGS1/JGS2/JGS3 to avoid a decrease in transmittance due to incorrect material selection.  

-Solution to insufficient cutting accuracy: eliminate common machining defects such as edge breakage, large dimensional deviations, and rough edges.  

-Resolve delivery instability: Provide customized services with multiple specifications, quick response, and stable delivery from small to large quantities.  

-Resolve post-processing difficulties: Deliver finished products directly without the need for users to perform secondary trimming, drilling, or polishing.

-Surface quality controllable: The surface roughness after cutting is Ra ≤ 0.8 μ m, and can be polished to Ra ≤ 0.2 μ m.  

-Batch consistency: Full size inspection report, each piece can be traced.  

-Quick quotation and delivery: Standard drawings can be quoted within 24 hours, and regular thickness can be delivered within 5-7 days.

Solve practical problems for users

-Problem 1: The JGS1 window panel purchased has a broken edge, which affects its sealing performance.  

Solution: We use slow cutting and edge chamfering polishing, with edge breakage controlled to be less than 0.05mm.

-Problem 2: Inconsistent thickness of quartz plates from different batches leads to optical path deviation.  

Solution: Each batch of 3D dimensions will be sampled and a tolerance analysis report will be provided.

-Problem 3: Unable to find manufacturers willing to do irregular cutting.  

Solution: We support CAD drawing customization, with no issues for irregular shapes, small apertures, or thin plates.
