Abstract:
1. An apparatus to calibrate an optical instrument and warm a distal portion of said optical instrument comprising: a heat conducting tube capable of receiving said distal portion, said heat conducting tube comprising a double walled cylindrical tube having an internal wall, external wall, upper surface, open distal portion, and a central cavity, an aperture extending from said upper surface sized and shaped to receive said distal portion of said optical instrument; a cap sized to attach to said distal portion of said double walled cylindrical tube; an insulation layer between said internal wall and said external wall of said double walled cylindrical tube; a heating element thermally coupled to said tube, said heating element enclosed within said central cavity and thermally coupled to said insulation layer; and a whitening element within or at a distal end of said tube that enables white balancing of said optical instrument, wherein said whitening element is located in a distal portion of said aperture, such that said distal portion of said optical instrument abuts said whitening element and light from said optical instrument is reflected off said whitening element back to said optical instrument in order to achieve white balancing of said optical instrument.
