📩 Request a Quote 📞 Contact Engineering Team❓ Frequently Asked Questions
What groove density should I choose for my spectrometer?
Lower groove density (300–600 lines/mm) provides wider spectral range; higher density (1200–2400 lines/mm) offers better resolution but narrower range. Contact us with your wavelength requirements for selection support.
Do you offer stock items for immediate delivery?
Yes, 25×25 mm, 35×35 mm, and 45×45 mm in 600/1200 lines/mm are typically in stock and ship within 1–3 business days.
What is the typical diffraction efficiency?
Our gratings achieve 70–85% absolute efficiency at the blaze wavelength, depending on coating and groove profile.
Can I get a sample for testing?
Yes, we offer single-piece samples for R&D validation. Contact our team to arrange.
What is your MOQ for custom gratings?
Custom gratings: 5 pieces minimum. Standard stock gratings: 1 piece.
What is the lead time for custom orders?
Typically 10–15 working days for custom gratings, depending on complexity and coating requirements.
Do you provide efficiency test reports?
Yes, each batch of gratings can be supplied with diffraction efficiency test curves upon request.
