Colours glass delicate shades ranging from pure violet through wine-red and warm gray. Light transmitted through such glass shows unusually sharp absorption bands. The glass is used in astronomical work to produce sharp bands by which spectral lines may be calibrated. Glass containing neodymium is a laser material in place of ruby to produce coherent light.Packing   Q: Are you trading company or manufacturer ?A: We are factory.Q: How long is your delivery time?A: Generally it is 5-10 days if the goods are in stock. or it is 15-20 days if the goods are not in stock, it is according toquantity.Q: Do you provide samples ? is it free or extra ?A: Yes, we could offer the sample for free charge but do not pay the cost of freight.Q: What is your terms of payment ?A: Payment=1000USD, 30% T/T in advance ,balance before shippment.     /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
