Conoptics conservatively estimates transmission at 85%. Insertion loss is typically due to absorption, crystal cut and AR coatings. Generally speaking we expect a small loss per interface (windows and crystals). Also note that the shorter devices which use one or two crystals will have a slightly higher transmission than the four crystal devices. If you need a lower reflectivity, we offer custom coatings. Call us for more details.
