ABSTRACT:
A transilluminator including a housing with a top wall having a UV-transmissible window and an upwardly extending projection. A UV light source is supported within the housing for transmitting UV light through the window and a UV-blocking cover with a hinge assembly is provided for movement of the cover between a blocking position and a non-blocking position. The hinge assembly has an undercut, and the protector plate includes a rearward portion which extends into the undercut when the plate is positioned over the window. The plate also includes a forward portion having an aperture through which the projection extends when the plate is positioned over the window. The plate is secured to the top wall by sliding the rearward portion of the plate into the undercut and then lowering the forward portion of the plate so that the projection extends into the aperture. The plate is removed by raising the forward portion of the plate so that the projection is removed from the aperture and then sliding the rearward portion of the plate out of the undercut.
