product description

Barium fluoride crystals larger than 120 mm in size can be monocrystalline or polycrystalline. We can provide 50 pieces of polycrystalline barium fluoride material of D140*30mm per month, the maximum size of polycrystal can reach 320mm; 100 pieces of monocrystalline material of D100*20mm per month, the maximum size of monocrystal is D130mm.

Applications :

Polycrystalline 170mm bar, monocrystalline 130mm, monocrystalline blank slices, polycrystalline open ball blanks

Product Advantage :

Formability: Can cut/round/ball/polish D360mm lenses
Surface finish: Ra<5nm; Orienting capability: 111, 100, 110

Product Parameters :

What is the surface finish of the blank D140*30?
The circumferential scratches on the column surface are less than 5 inside, no visible chipping on the polished surface, chamfering 0.5-1.2 mm
Diameter tolerance can be +0.0, -0.05; thickness tolerance: +0.1, -0.1.
Surface treatment: W28/40

Can you process BAF2 platform lens of D160?
The maximum processing diameter of the lens is D360mm; so D160 can be processed, the standard capability is 60-40 finish; PV<1L@633NM; because the material is soft, it is recommended that the thickness tolerance is +/-0.05mm. Can we supply BAF2 blanks for D300? If the material size is more than 200mm, it is a custom product; we can provide 300mm polycrystalline BAF2, single crystal maximum size is 200mm; the lead time is usually 3-6 months.
