About this product
AR-Coated Glass — Projection is a custom-manufactured Dichroic Glass, produced to order at our Hangzhou workshop.

Dichroic glass carries an interference coating that reflects one band of colour and transmits another. Because the effect comes from thin-film interference rather than absorption, the glass stays cool under intense light.
