High Performance Measurements of Sample Reflectivity with the 10Spec

The PIKE Technologies 10Spec is an optimized specular reflectance accessory meant for high-performance measurements of sample reflectivity. It creates a collimated beam to illuminate the sample area such that the reflectivity measurement is done at a uniform 10 degree angle of incidence and not an average of angles generated by a focused beam accessory design. At a near-normal angle, the polarization effects on reflectivity are reduced. The optics is enclosed to allow for purging.

The 10Spec can also be used to measure the reflectivity of glass. It may also be used to measure near-normal reflectivity of a broad range of surfaces including reflecting optics, military devices, anti-reflective (AR) coated surfaces and other reflecting and non-reflecting materials.

There are two versions of the 10Spec available. The standard version is 118 mm tall while the Extended Height 10Spec is 205 mm tall, which positions the sample above the top of the FTIR instrument. The Extended Height 10Spec is built to house samples that are too large to fit inside the confinements of the sample compartment.
