Hi friends,
Need a little help here . How do I solve these?
1. Find the vertical and horizontal prismatic effects produced by decentring the lens R-2.50DS / +5.00DC @135 12mm upwards.
Do I take x as 0 while using the formula method ?
How does it correlate while solving by the graphical method?
2. How much prism must be incorporated in the lens L-4.00 DS / -2.00 DC @ 140 in order to shift the optical centre 6mm inwards ?
Do both the problems incorporate the same concept? Pls pls kindly help
