Handle by the edges only — coating surface contact will degrade reflectance and damage threshold. Clean with high-purity acetone or methanol using the drop-and-drag technique; never wipe across the coated face. Avoid extreme temperature gradients that can cause stress birefringence in the substrate.\u003c\/p\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":47473870831770,"sku":"HD1715-25.4-6.35","price":610.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/15_08235368658009573_350.png?v=1772511905","url":"https:\/\/waveqvanta.com\/products\/2000-5000nm-chirped-mirror-100fs","provider":"WaveQuanta","version":"1.0","type":"link"}
