PURPOSE:To obtain a bonded prism in which the surface of the prism can be coated with a reflecting film, a BS film, a PBS film or the like even at a high temperature after prism have been bonded. CONSTITUTION:When a plurality of prisms 1, 2 are bonded at their optical faces, a fusing glass is used as a bonding agent. Thereby, the surface of the bonded prisms 1, 2 can be coated with various kinds of optical films at a high temperature after the prisms have been bonded, and the function of the bonded prisms 1, 2 can be increased. In addition, the fusing glass is filled into a groove on the bonding face of at least one out of the prisms 1, 2 and the prism is made to function as an optical element after the fusing glass has been solidified. Thereby, the function of the bonded prisms 1, 2 can be increased.

Abstract:
PURPOSE:To continuously and stably perform high accurate mirror surface grinding work by setting deflection of a conductive grindstone, drive-rotated by a spindle, to 1/3 times or less the mean size of abrasive grains. CONSTITUTION:Deflection of a conductive grindstone 5, drive rotated by an air spindle 1, is set to 1/3 times or less the mean size of abrasive grains. Consequently, a scratch and plucking or the like, caused by a metal bond coming into contact with a workpiece 6, are eliminated to cause a cutting edge of the fine abrasive grain to effectively act on a fragile material. Accordingly, stable and high accurate mirror surface work is continuously performed by a synergetic effect with removal of blinding by electrolytic dressing of an electrolytic electrode 11.
