Accessories are essential tools to simplify measurements and increase the versatility of any modular spectroscopic setup. A wide selection of accessories enables more accurate results and a great number of configurations for up-coming measurements. In order to create the ideal setup for your spectroscopic measurements, Sarspec offers a number of high-quality accessories such as cuvette, solid and probe holders, collimating lens, flow cells, and reflectance standards.

Flow Cells

Flow injection analysis cells are the ideal solution for absorbance and fluorescence measurements of a continuous flow system.

In-Line Filter Holder

The inline filter holder is a convenient solution for absorption, transmission and reflection measurements that is inserted between two optical fibers for filtering or attenuating the illumination light.

Reflectance Standards

A set of standards designed for specular and diffuse measurements of solid surfaces over a wide range of wavelengths.

Collimating Lens

Collimating lens are key optical elements used to adjust the illumination and collection efficiency that can be easily coupled to optical fibers through SMA 905 connectors.

Solid Sample Holder

Solid sample holder is the perfect solution to use with absorption and transmission configuration for measuring solid samples such as filters, glass samples, and powder pellets.

Cuvette Holders

Cuvette holders are the perfect accessories for absorbance and fluorescence measurements of non-opaque solid and liquid samples. To increase the versatility, accuracy and reliability of a cuvette-based absorbance and fluorescence setups, Sarspec offers three different types of cuvette holders with each being designed for a specific measurement setup.

Standard Cuvette Holder

Standard cuvette holder is the ideal accessory for cuvette-based absorbance and high-emissive fluorescence measurements. With an operational range from 190 to 2500 nm, standard cuvette holder includes two 6 mm collimating lenses with SMA 905 connectors and adjustable focus to maximize light throughput.



Multipurpose cuvette holder is the perfect accessory for cuvette-based low-light level fluorescence measurements. With an operational range from 190 to 2500 nm, multipurpose cuvette holder includes two 12.7 mm collimating lenses with SMA 905 connectors and adjustable focus and offers the possibility of adding SiO2 coated aluminium mirrors to enhance the excitation and fluorescence signal.



Q-Pod cuvette holder is a Peltier-controlled support with magnetic stirring for temperature controlled absorbance and fluorescence measurements. A fused silica lens system with SMA 905 connectors provides wide connectivity to optical fibers while the temperature is controlled via Bluetooth wireless or USB cable. Q-Pod allows the temperature to be set between -35°C and +110°C with an accuracy of 0.05°C.
