Product Model: 61-6947-97
Product Brand: SIGMAKOKI CO., LTD.
Features
- This is a highly reflective mirror with an adjustment mechanism, in which a surface accuracy guaranteeing mirror (HTFM) is set in a kinematic mirror holder and bonded so as not to apply stress to the mirror.
- This product guarantees the surface accuracy of the mirror after incorporating and bonding the mirror to the holder.
- There are two types of mirror holders: high-stability type (MHG-HS) and mass-produced type (MHG-MP).
- This product can be ***d to configure optical systems, interferometers, etc. that require high wavefront accuracy.
- The mass-produced model (MHG-MP) has an adjustment screw locking mechanism.
- Can be attached to rod RO -** (sold separately) or post stand PS -** (sold separately).
- The reflectance wavelength characteristic is shown in the graph of the Surface Accuracy Guarantee Mirror (HTFM).
- * The mirror surface comes out 2 mm in front of the holder mounting surface.
- * Once the glued mirror is removed, the surface accuracy of the mirror is not guaranteed.
- * If a strong impact is applied to the holder or mirror, the surface accuracy of the mirror may be deteriorated.
- * The center of rotation of the mass-produced type (MHG-MP) is located outside the mirror (the fulcrum of the holder).
- * Use the rod mounting plate (MHG -** BPRO) when fixing the Takayasu standard (MHG-HS) to a flat surface.
- * The optical axis is 10 mm higher when using the rod mounting plate (MHG -** BPRO).
- * Surface accuracy guarantee data is not attached to the product.
