Long Optical Pin

Product Code : JA-LOE-7918

The Long Optical Pin (SKU JA-LOE-7918) listing covers optical pins supplied in packs of 100, used as objects and sight markers in ray-tracing practicals. Students stand the pins upright in a drawing board and line them up by eye to trace the path of light through a glass slab or prism or its reflection in a mirror, which makes optical pins for ray tracing one of the most used consumables in a school optics laboratory. JaincoLab supplies them for school and college physics practicals.

Specifications

The product is supplied as a pack of 100 long optical pins; pin length and finish are confirmed on the quotation.

Uses of optical pins for ray tracing

Optical pins are used in the pin method of ray tracing, in which pins are aligned by eye so that each ray can be drawn on paper and the angles of incidence, reflection and refraction measured with a protractor.

  • Verifying the laws of reflection with a plane mirror
  • Tracing refraction through a rectangular glass slab to find refractive index
  • Finding the angle of minimum deviation of a prism
  • Locating images by the no-parallax method
  • CBSE and ICSE class 9 to 12 light practicals

Scope of supply

The listing covers one pack of 100 long optical pins. Drawing boards, mirrors, glass slabs, prisms and quantities are confirmed on the quotation.
