The Holmium Oxide Glass Filter is a neutral density glass filter used to check the wavelength accuracy of a spectrometer. This filter ships standard with the UV Starter Pack (L6000573).

For our NIST traceable product, please see part number N1010545.

The Holmium Oxide Glass Filter is a wavelength accuracy standard for all LAMBDA UV/Vis and UV/Vis/NIR spectrometers. The filter is mounted on a precision aluminum spring mount and ships in a re-usable, UV-protective storage container with a Certificate of Calibration.

The Pharmacopeia Solutions Reference Materials kit consists of six solutions (two reference and four test) in sealed cells designed for use in standard 10 mm cuvette holders. These solutions verify calibrations in all LAMBDA spectrometers in accordance with Pharmacopoeia monographs.

The Stray Light Solutions Reference Materials kit consists of four solutions (one reference and three test) in sealed cells designed for use in standard 10 mm cuvette holders. These solutions verify stray light calibrations for all LAMBDA spectrometers.

The Photometric and Wavelength Accuracy Reference Materials kit includes a set of reference standards used to verify the ordinate and abscissa accuracy of the LAMBDA spectrometers. The neutral density glass filters included in this kit are A2LA ISO 17025 accredited.

PerkinElmer offers a rapid recertification process that includes:

• Inspection and cleaning of the reference materials
• A state-of-the-art recertification laboratory
• A Certificate of Recertification

We return ship your recertified standards in ten business days or less from the time we receive them. Shipping is free.

The Disposable Reference Mirror for Reflectance Spectroscopy is a 40 mm square aluminum mirror with a magnesium fluoride protective coating. It is a secondary standard and is calibrated for 250 to 2500 nm, according to GLP regulations. It comes with spectral data for %RC Reflection corrections.

Note: This mirror cannot be recalibrated.

The White Reference Standard is used to establish baseline reflective readings for the 50 mm Transmission-Reflectance Spheres (N4101011).

The 1.25 in White Calibration Material is a Spectralon^® diffuse reflectance white plate standard for the LAMBDA spectrometers. High performace (98%).

This set of Diffuse Reflectance Reference Materials has eight calibrated neutral disks with reflectance factors of: 99%, 80%, 60%, 40%, 20%, 10%, 5%, and 2%. All disks are 1.25 inches in diameter. Qty. 8

With the Single Recalibration Kit, PerkinElmer offers a recalibration service for single reference materials, such as the Holmium Oxide Glass Filter. PerkinElmer provides recalibration services on site at their UV Reference Materials Laboratory, which is ISO/IEC 17025:2005 Accredited. The recalibrated material is returned to you and includes a Certificate of Calibration identifying the recalibrated frequency.
