Design for Manufacturability Accuflect B6
1. Maintain at least a 3mm wall thickness where possible to minimize breakage in manufacture and use.
2. Do not design seal surfaces into the reflector. Rely on the metallic pump chamber or flow tubes to provide necessary sealing surfaces.
3. UV filter glass can be incorporated to improve laser rod lifetime. The flat glass sheet can be mounted in slots on the inner reflector surface. Slots should be at least 1 mm deep to adequately trap the filter glass. 4. Do not use threaded mounting holes in the reflector. 5. Limit reflector size to 75 mm diameter or square by 250 mm long if possible. Multi-part designs for larger geometries can be accomodated.
6.
Design for a maximum fillet radius of .5 mm Accuflect G6 1. The same notes listed for Accuflect B6 apply except with a few exceptions. 2. Design for open tolerances. A general rule is +-0.3mm.
3. Passive mounting using compliant components is suggested. Components such as o-rings and springs work well.
4. Provide a support surface for holding the ceramic during glazing. Relieved areas 1mm deepwork well. Flat bottom grooves extending across or along the part work best. 5. Design for a maximum fillet radius of 1 mm. 6. Assume mounting surfaces are not flat. Flatness may vary as much as .15 mm so strive for three point registration. 7. Radius all external sharp edges at least .7 mm.
Optical Design 1. Maintain at least a two mm thick wall to minimize light leakage through the Accuflect material.
2. If a split design is being considered, use lap joints to minimize light leakage. 3. Keep the inside shape of the reflector simple. Oval shapes are good. There is no need for complex or critically toleranced paraboloid or ellipsoid focusing geometries since the reflected light is scattered by the reflector.
4. These are designed to be close coupled reflectors. Keep reflector walls as close to lamps and laser rods as possible consistent with adequate cooling. One mm clearance is a good starting point for design. 5. Avoid split designs with Accuflect G6. The glaze is clear and may result in excess light leakage through the joint.
Low Cost Design 1. Keep external shapes simple. Cylinders or rectangles are best. 2. Avoid drilled mounting holes. Look for mounting techniques other than screws. 3. Avoid selective surface glazing with Accuflect G6.
