An apparatus and method for producing a substantially straight instrument image is provided. The apparatus and method for producing a substantially straight instrument image, according to the present invention includes a curved slit. The curved slit may be formed in a light beam controller. The curved slit is capable of admitting a light beam into the instrument. The instrument parameters associated with optical devices located in the instrument in the path of the light beam are determined. One or more formulae are used to transform and process the instrument spectral parameters to determine the shape or curvature of the curved slit.
