The ZWO D21 and D25 IR-Cut Protection Windows work with ZWO astronomy cameras to protect the sensor from dust and humidity. Transmission is >90% at visible wavelengths from 400nm to 675nm approximately. The window also removes IR light that may not come to a tight focus, especially when imaging with refractors, to help you get sharper images and pinpoint stars.
