ATR Optical Elements(ATR光学素子)

spectralSys_aTROpticalElements Spectral Systems offers a comprehensive set of ATR crystals for infrared sampling. They specialize in ATR coatings to optimize the performance and IR throughput for ATR applications. They manufacture and design proprietary ATR crystals.

AMTIR 50 × 20 × 2 〜 80 × 10 × 3 45° Trapezoid
45° Trap, Aluminized TROUGH
60° Trap, Aluminized TROUGH
Amorphous material transmitting IR (AMTIR) has very low water solubility and good chemical resistance – particularly to acids. It generally performs well in a pH range of 1-9. Although AMTIR contains arsenic and selenium, it is generally considered safe to handle. Coated versions of their AMTIR ATR crystals are available for improved IR throughput and enhanced seal within the ATR crystal plate.

Germanium (Ge) is a high refractive index material (4.0 @ 10 microns) which provides shallow depth of penetration useful in some ATR applications. It is relatively hard and resistant to most acid and basic samples. The long wavelength cutoff of Ge will limit spectral range for multiple reflection ATR crystals to about 700 cm (depending upon pathlength). Coated versions of our Ge ATR crystals are available for improved IR throughput and enhanced seal within the ATR crystal plate.
KRS-5 50 × 10 × 3 〜 50 × 20 × 3 45° Parallelogram
45° Trapezoid
Thallium Bromoiodide (KRS-5) ATR crystals are a medium refractive index material (2.37 @ 10 microns) with excellent long wavelength coverage in the infrared spectral region. It is non-hygroscopic with very good chemical resistance; however, KRS-5 will occasionally exhibit cold flow behavior. KRS-5 is extremely toxic and is absorbed through the skin and should only be handled with glove protection.

45° Aluminized TROUGH
ZnS 50 × 20 × 2 〜 80 × 10 × 3 45° Trapezoid
30° または 55° Aluminized TROUGH
Zinc sulfide (ZnS) is a relatively hard material and is resistant to thermal and mechanical shock. It is insoluble in water but can be attacked by strong acids and bases. ZnS is classed as a GRAS material. Its spectral range is more limited than ZnSe in the long wavelength region. Coated versions of their ZnS ATR crystals are available for improved IR throughput and enhanced seal within the ATR crystal plate.

Zinc selenide (ZnSe) is a widely used ATR crystal material and is a relatively hard and brittle material. It is insoluble in water but is attacked by strong acids and bases. ZnSe has a good mid-IR spectral range reaching to about 630 cm-1 for multiple reflection ATR crystals at the long wavelength side of the spectrum (depending upon IR beam pathlength). Coated versions of their ZnSe ATR crystals are available for improved IR throughput and enhanced seal within the ATR crystal plate.
