Abstract:
Telescope Objective is very essential component of overall optical payload design of CubeSat [1] .In this paper, a design of objective operating in visual band is done using ZEMAX software. The refractive design is chosen since reflective one provides smaller FOV. In order to get high resolution we picked up a detector with pixel pitch of 3.6 µm with a high MTFA value of .5 at spatial frequency resolution boundary (Nyquist frequency) of 139 cycle/millimeter, in order to cover wide FOV this detector pixel pitch and small focal length value provides so. The limitation to this design was size of this objective as in the 3U CubeSat, the objective uses 2U as other papers show we had a restrict on the size only limited to 1U and every U is 10*10*10 cm so in this paper we have managed to avoid this limitation on size presenting an objective design with very high performance image within the pixel pitch of chosen OV7670 sensor 3.6 microns pixel pitch
