DRA-EV-300 Diffuse Reflectance accessory

The DRA-EV-300 is an integrating sphere accessory with an upward viewing reflectance port and a vertical mount transmittance port for maximum ease of use for both types of measurement.

Innovative, Easy to Use Sample Placement

Mounting a reflectance sample is as easy as placing it over the port on top of the accessory. Unlike vertical type mounts that use a sprung clamp to hold the sample, the upward viewing configuration of the DRA-EV-300 uses gravity to hold the reflectance samples in place.

Scattered transmittance samples mount either under the spring clips or on top of the step at the transmittance port - whichever method is more appropriate to your sample.

Increase Reproducibility and Integrity of Samples

• reproducibility of your data is increased because no pressure is needed to mount the sample
• integrity of your sample surface is not compromised
• delicate samples can be measured without fear of damage or crushing
• samples are protected from scratching by a Mylar® coating on the surface of the sphere casing
• reflectance samples up to 10 cm thick and 14 cm wide can be measured
• samples in bottles or beakers can be measured by simply placing the bottle over the reflectance port

Snap-in Accessory Mounting

The DRA-EV-300 mounts directly in the sample beam and utilizes the Thermo Scientific Evolution 300 built-in detector, eliminating mirrors to align or cables to attach. The hot-swappable accessory give you the advantage of not having to restart the instrument to switch between accessories. Simply snap the baseplate into the kinematic mount in the Evolution 300 sample compartment, record a baseline and you are ready to measure.
