Abstract: New families of two mirror unobscured telescopes with compact Schiefspiegler, eccentric pupil Cassegrain geometries, incorporating aspheres, tilted and decentered secondaries, and tilted decentered focal surfaces. These variables allow control of focal surface tilt. All embodiments, from f/5 to f/16, are totally reflecting, fully baffled systems, with wide diffraction limited FOVs and unobscured aperture MTFs. Systems optimized with the focal plane normal to the gut ray are well suited for visual and general use. They can incorporate a variable iris for f/number control and allow focusing along the gut ray with minimal field tilt. Systems optimized with a fixed focal plane tilt are well suited for high resolution, wide field collimators and IR scene generators. Any light reflected at focus can be trapped, eliminating Narcissus or “cats eye” effects. Additionally, this reflection can be used to provide a uniform “background” irradiance field.

Abstract: Reticles and scopes using reticles are provided with increased visibility in low-light conditions by illuminating the reticle using the light emitted by a quantity of photoluminescent material. The photoluminescent material may be placed on the reticle itself or emit light which is cast onto the reticle.

Alternatively, the light may be transmitted directly into a disc of optical material which has an area etched into a reticle pattern whereby the transmitted light escapes from the disc through the etched out portion and provides an illuminated reticle pattern which is visible in low light conditions.

The device is composed of a material which is capable of transmitting light from a remote source. Light from a visible indicator such as an LED is transferred through at least one outer flat to an inner flat of the device. The inner flat provides a signal to the user that the power supply is low.
