What's New

 

 

Non-contact displacement and vibration sensor capable of ultra-high resolution of 0.08nm with high speed response. In the world of ultra-precision equipment which demand movements in units of nanometers, continuous and sccurate detection of movement status is essential. The DS - 80 employs the Michelson interference method, discovered in the Michelson-Morley experiments, to make highly accurate measurements based on the laser's wavelength. Canon has realized a Michelson interferometer, including both the light source and sensor, in a space of only 47 x 32 x 19 mm using its precision optical technology.

FEATURES

  • In the world of ultra-precision equipment which demand movements in units of nanometers, continuous and accurate detection of movement status is essential.
  • The DS-80 employs the Michelson interference method, discovered in the Michelson-Morley experiments, to make highly accurate measurements based on the laser's wavelength.
  • Canon has realized a Michelson interferometer, including both the light source and sensor, in a space of only 47x32x19mm using its precision optical tech-nology. Canon has created two types of sensors - A-type with a working distance of 10mm and B-type with a working distance of 2.5mm - to support a wide range of needs.

INSTALLATION CAUTION

  1. Start up the exclusive software of Micro Laser Interferometer DS-80, then select Head Adjustment mode.
  2. Position the sensor head toward the measurement object so as to make the Lissajous pattern as large as possible.
  3. If the sensor head is detecting an oscillation with an amplitude greater than 325nm, the Lissajous function will trace a circle.
If the amplitude is less than 325nm, a complete circle cannot be drawn.
