This diamond anvil design is essentially an optimised Drukker cut anvil where the height/base ratio has been maximised (for a particular size of diamond).  The smaller the height/base ratio is, the lower the maximum load the anvil will sustain.

Drukker (standard) design diamond anvils have been shown (c.f. M. Seal, High Temperatures-High Pressures, vol 16, pg. 573 [1984]) to have optimum strength.

All type IIas anvils are Raman ultra-low fluorescence and ultra-low birefringence, (100)-oriented and particularly suitable for IR and highly demanding Raman spectroscopy.


Material: synthetic type IIas HPHT diamond (also referred to as type IIas).
Cut: Diacell design
Girdle diameter, X: 3.10 mm
Anvil height, H: 1.70 mm


This diamond anvil is used in the Diacell HeliosDAC, OmniDAC range, CryoDAC-Mega and LeverDAC-Mega.

Type IIas anvils are required for any Infrared and particularly demanding Ultra Low Fluorescence background spectroscopy studies, but can also be used for any other applications.
