Bristol Instruments Inc. has expanded the operational wavelength range of the infrared version of its 621 laser wavelength meter. Originally 1.5 to 4.0 μm, the device’s range now covers up to 5.0 μm, making it suitable for high-resolution laser spectroscopy. Two models are available: The 621A measures absolute wavelength with an accuracy of ±0.2 parts per million, and the 621B, ±1.0 parts per million. Visible and near-IR versions also are available.
