    Thorlabs lists either 100 mm or 150 mm focal length 50 mm diameter spherical mirrors for less than $100 as stock items but we designed for 125 mm focal length (and it was only while drafting this conclusion that the lack of 125 mm focal length as a stock item came to the author's attention).

    Telephoto lenses - 150% longer focal length that most normal lenses. *About 50% longer-than-normal lenses for the format; for example a lens greater than about 12mm for a 1/3 inch sensor camera or greater than about 70mm for a camera with a Super 35 sensor would be considered telephoto.

    AC voltage is 120 volts RMS. The Puntino uses a 46 mm focal length collimator lens assembly (plano-convex lens and achromat) to form an 9 mm diameter pupil image of the primary mirror on the Shack- Hartmann lenslet array. The pitch of the lenslet array is 0.6 mm and the lenslet focal length is 40 mm.

  • Collimator - Wikipedia

    In optics a collimator may consist of a curved mirror or lens with some type of light source and/or an image at its focus.This can be used to replicate a target focused at infinity with little or no parallax.. In lighting collimators are typically designed using the principles of nonimaging optics.. Optical collimators can be used to calibrate other optical devices to check if all elements ...

    Telephoto lenses are popular for photographic lenses because the distance from the front surface of the lens to the image plane is less than the focal length. This makes the camera more compact. The telephoto ratio (TR) is defined as the ratio of the overall length of the lens divided by the focal length.
