Material Science Insights
Why Custom Quartz Slides Outperform Standard Borosilicate in High-NA Metrology
In super-resolution fluorescence microscopy, deep-ultraviolet (DUV) inspection, and quantum electrodynamics, standard soda-lime and borosilicate slides cause significant optical distortion. Our custom fused silica microscope slides resolve these physical limitations through chemical purity, atomic homogeneity, and structural resilience.
Zero Autofluor Neutrality
Synthetic JGS1 fused silica features virtually zero background autofluorescence when excited across 248 nm, 355 nm, and 405 nm laser wavelengths, maximizing signal-to-noise ratios in single-molecule localization microscopy (SMLM).
Extended DUV & NIR Transmittance
Delivers continuous optical transmission (>92% uncoated) spanning 185 nm deep-ultraviolet to 2,500 nm near-infrared. Eliminates ultraviolet cut-off boundaries common in conventional float glass.
Ultra-Low Thermal Expansion
With an extremely low thermal expansion coefficient of 5.5 × 10⁻⁷ /°C, our quartz microscope slides prevent focal-plane drift and thermal lensing during intense, prolonged pulsed laser irradiation up to 1,100 °C.

Procurement & Engineering Q&A
Frequently Asked Questions for Custom Quartz Slides
Clear technical answers regarding raw material selection, manufacturing tolerances, lead times, and global shipping.
What is the primary optical difference between JGS1, JGS2, and JGS3 quartz slides?
JGS1 is synthetic fused silica offering superior optical transmission from 185 nm to 2,500 nm with negligible autofluorescence, ideal for deep-UV laser and single-molecule fluorescence. JGS2 is optical quartz suitable for visible to near-IR optics (220–2,500 nm). JGS3 is infrared-grade fused quartz with ultra-low OH- content (<5 ppm), ensuring zero absorption dip across the 2,700 nm water absorption band.
Can you manufacture custom dimensions, thicknesses, and edge profiles?
Yes. We fabricate slides beyond standard 75 × 25 mm (3" × 1") dimensions. We routinely produce circular, square, and custom CAD geometries with thicknesses from 0.15 mm (No. 1.5 coverslip equivalent) up to 10 mm. Edge options include ground matte edges, 45-degree chamfers, and fire-polished edges for cleanroom safety.
What surface quality and flatness standards do you achieve?
Our precision double-sided polishing line delivers surface quality down to 20-10 or 10-5 Scratch-Dig (MIL-PRF-13830B), surface roughness Ra < 0.5 nm (measured via Atomic Force Microscopy), and optical flatness up to λ/10 @ 632.8 nm over the clear aperture.
How do you clean and package quartz slides to prevent particulate contamination?
Finished slides pass through a multi-stage ultrasonic deionized water wash with neutral and acidic surfactants, followed by IPA vapor drying. They are vacuum-sealed inside antistatic, dust-free Class 1,000 cleanroom waffle trays or lens paper sleeves to arrive cleanroom-ready.
What are your typical turnaround times for prototypes and batch production?
Standard custom prototype orders (5–50 pieces) typically ship within 5 to 7 business days from drawing sign-off. High-volume repeat OEM production runs (1,000–50,000 pieces) require 2 to 3 weeks, accompanied by lot-specific inspection and transmission certificates.
