Optical Testing or Optical Alignment products are used in a variety of applications to test, observe, or calibrate optical or illumination systems or mechanical surfaces. Optical Testing or Optical Alignment products can be used to test a variety of attributes, including surface accuracy, index of refraction, concentricity, parallelism, or lumens. Optical Testing or Optical Alignment products can include autocollimators, reflectance or integrating spheres, Schlieren systems, wavefront sensors, or abbe refractometers.
Edmund Optics offers a wide variety of Optical Testing or Optical Alignments products. Autocollimators can be used to test surface parallelism. Close focus telescopes are ideal for aligning optical systems. Reflectance spheres are used to measure hemispherical or diffuse reflectance, or the UV resistance, color, or radiant heat transfer of a sample. Integrating spheres can be used to measure light sources, calibrate sensors, or test optical lenses. Schlieren systems are ideal for applications such as determining refractive index, fluid or air flow, internal characteristics or glass, or flame analysis.
