In perfect domes the convex radius is equal to the sum of the dome thickness and concave radius, respectively uncoated or with an antireflection coating. Slight departures from that rule are sometimes desired. These protection covers are high quality optical products which are produced through precision polishing. They ensure clear, distortion free protection for your underwater camera objective or other sensitive equipment.
Yutai Optics provides domes from glass, quartz, depending on the temperature, shock and scratch resistance required. These items will be manufactured on customer request only. We recommend thickness at least 4mm for customer as production cost will be better than the thinner ones.
BK7 is the most commonly used optical glass, and BK7 domes are a popular optical protection element suitable for protecting internal optics or sensors while providing good optical performance. Selection requires a trade-off between performance and cost based on specific needs.
