An apparatus may have a light source configured to generate light, a reflector configured to collect the light and direct the light in a desired direction, a spectral filter assembly configured to receive the light from the reflector. The spectral filter assembly may have a stationary frame and a plurality of filter elements supported by the stationary frame. Filter elements of the plurality of filter elements may simultaneously filter a desired quantity of light within wavelength band to provide a filtered output light beam. A homogenizer may be configured to receive the filtered output light beam and produce a homogenized light beam having a substantially uniform irradiance distribution across a cross-section of the homogenized light beam.

Optical source assembly suitable for use as a solar simulator and associated methods

A method and apparatus for generating an image. Light is passed though an opening of a housing. The light has an intensity. At least a portion of the light received through the opening is increased using an intensifier unit to form intensified light. The intensified light is converted into a number of signals for the image using an image detection system located inside of the housing.

Intensified pinhole camera system

An optical beam homogenizer having an adjustable homogenizer chamber for selectively producing different sized homogenized output beams and related methods in accordance with one or more embodiments is described herein.

Variable sized optical beam homogenizer and method

In one embodiment, a device for capturing radiation includes: a panel defining a plurality of double wedge chambers, wherein each double wedge chamber includes a first wedge-shaped chamber that tapers into an opening for a second wedge-shaped chamber, and wherein a longitudinal axis of the first wedge-shaped chamber is not collinear with a longitudinal axis of the second wedge-shaped chamber.

Planar beam dump

In accordance with an embodiment of the present invention, an optical system includes two tilted planar elements each having two surfaces for which the sign of the slopes of at least three of the four surfaces that an incident beam encounters are the same and which, when inserted into the path of the incident beam produces an output beam having no angular deviation and essentially no lateral deviation from the incident beam path.

Compact self-compensating beam splitter apparatus and method of using

An exemplary calorimeter includes a body configured to capture radiation generated by a source of the radiation, such as without limitation a laser, and absorb energy from the captured radiation. The calorimeter is simple to manufacture, operate, and maintain and is compact, highly accurate, able to withstand high power beams, and self-calibrating. NIST traceable electrical wires are used for the measurement. No fluids are used during measurements of the input radiation. A simple built in fluid or gaseous cooling system may be used post-measurement to reset the calorimeter temperature back to ambient for repeated measurement capability.

Simple high accuracy high energy calorimeter

A device for capturing radiation includes multi-axis, multiple chambers with two dimensional geometry. A first chamber has a first axis and is configured to receive a beam of radiation and absorb a portion of the beam of radiation. A second chamber has a second axis that is not collinear with the first axis. The second chamber is configured to receive at least a portion of the beam of radiation and absorb at least a portion of the beam of radiation. In one preferred embodiment, the second chamber terminates at a vertex. Additional chambers may be provided, as desired, with axes not collinear with either the first chamber, the second chamber, or any other chamber such that the plurality of chambers absorb substantially all of the radiation.
