Dove prisms are used as reflective prism inverting the image. Dove prism is shaped from a truncated right-angle prism. Normally, dove prisms are used in the parallel optical path based on critical angle principle to meet total internal reflection with limited FOV. A beam of light entering one of the sloped faces of the prism undergoes total internal reflection from the inside of the longest (bottom) face and emerges from the opposite sloped face. Images passing through the prism are flipped, and because only one reflection takes place, the image is inverted but not laterally transposed. A beam of light entering the sloped faces undergoes total internal reflection from the bottom surface, and emerges from the opposite sloped face. Also interestingly whtn dove prisms optical are rotated along longitudinal axis, the image rotates at twice the rate of the prism which have applications in fields such as interferometry, astronomy, and pattern recognition. Dove prisms can be also used as right angle prisms with sloped faces HR coated.

Truck access platforms are made out of brass which provide more durability and Much longer-lasting than a straight braced frame.3. Height of truck access platform is 200mm and it has Adjustable Locking Nylon Castors which make it manageable at rough or sloping areas.

Imagine a quaint town enclosed by mist and fog, which when cleared away, reveals winding pathways through dense forests. This is Coorg or Kodagu to the locals, and it will entice you with its picturesque landscapes, wooded slopes, and a lingering scent of wet mud and flora.

The trek involves steep slopes, gradual climbs, barren mountains, monstrous weather and high altitude. Continuous rain and snowfall makes the walk more difficult than it may seem. Rock climbing, snow trekking, waterfall crossings and wading through water bare foot is a common occurrence. One would require utmost stamina and fitness to complete the trail. Pin Parvati trek is the most beautiful and adventurous, because of its high Pin Parvati Pass which separates the Pin and Parvati valleys. Trek that takes one from the parvati valley in kullu to the pin valley in Spiti across the 5319-meter. One needs to be extremely fit and very well prepared for this trek as there is absolutely no habitation along its entire length.
