Sampling Accessories

Sampling Accessories Products

Ocean Insight has accessories for free space measurements, and solid or liquid sampling. Available in our online shop for added convenience.

Free Space Optics

Collimating Lens, Cosine Correctors, Spheres

Integrating Spheres

Integrating spheres are ideal for reflectance measurements of rough surfaces and measure sample spot sizes up to 8 mm. Integrating spheres also are available for irradiance measurements.

Collimating Lenses

Collimating lenses are curved optical lenses that allow users to control the field of view, collection efficiency and spatial resolution of their setup, and to configure illumination and collection angles for sampling.

Cosine Correctors

Cosine correctors are optical diffusers that couple to fibers and spectrometers to collect signal from 180° FOV. Correctors measure spectral irradiance of a plane surface in air or other media.

Lens Holders & Mounts

Ocean Insight offers optical lens holders, fixtures and mounts for manipulating collimating lenses in various measurement setups. Holders position lenses and can be adjusted to accommodate various samples.

Liquid Sampling

Cuvette Holders, Flow Cells and More

Cuvette Holders

We offer cuvette holders and cell fixtures for absorbance and fluorescence sampling. Both discrete and direct-attach holders are available and integrate seamlessly with our spectrometers, light sources and optical fibers.


Plastic and quartz cuvettes are available for absorbance and fluorescence. Quartz cuvettes are durable and versatile; plastic cuvettes are a low-maintenance alternative to quartz for absorbance measurements.

Flow Cells

Flow injection analysis cells are great for absorbance and fluorescence of fluids used in process monitoring, lab setups and teaching labs. Z-type cells are available in a variety of materials, pathlengths and internal volume units.

Absorbance Standards

Absorbance standards are handy for verifying the photometric accuracy of your spectrometer. Standards are packaged as UV or Vis kits, with a background reference for low, medium and high absorbance solutions.

Solid Sampling

Integrating Spheres, Filter Holders, Sample Stages

Reflectance Standards

Specular and diffuse reflectance standards are designed for measurement of sample surfaces. Standards are available for high or low specular reflectivity; diffuse standards come in Spectralon or PTFE materials.

  • Reflectance standards are available for diffuse or specular reflectance applications. To ensure best results, select a standard with reflectivity comparable to the sample to be measured.

Filter Holders/Filters

Ocean Insight offers accessories for controlling, filtering and attenuating light. Options include optical filters for high-pass, bandpass and balancing needs and holders for accommodating filters in optical setups.

Linear Variable Filters

Linear Variable Filters (LVFs) are great for setups where high pass, low pass or bandpass filters are required. LVFs are designed so you can move the transmission or blocking band through each filter’s wavelength range.

Sample Stages

Optical stages are versatile accessories for reflection and transmission measurements of flat substrates. Versions are available for single-point reflection and multipoint reflection/transmission measurements.

Raman Accessories

Sample Holders, SERS Substrates, Safety Glasses

Raman Sample Holders

Ocean Insight offers sample holders for Raman analysis of liquids and solids. The holders accommodate probes from 9.5 mm-12.7 mm diameter, plus 1 cm pathlength cuvettes, vials and SERS substrates.

SERS Substrates

Surfaced Enhanced Raman Spectroscopy (SERS) substrates amplify weak Raman signals by many orders of magnitude, enabling trace level detection of samples including pesticides and narcotics.

Raman Laser Safety Glasses

Safety glasses offer great protection from laser light without sacrificing visibility or comfort. Options are available for use with laser excitation wavelengths including 532 nm, 638 nm, 785 nm, 808 nm and 1064 nm.

Oxygen & pH Sensors

Optical Oxygen & pH Sensors

Optical Oxygen Sensors

Advances in sensor materials and optoelectronics have enabled novel optical sensors. The principle of operation is to trap an oxygen-sensitive fluorophore in a coating that’s applied to the tip of a fiber or an adhesive patch.

Adapters, Cables & Power Supplies

Adapters, Cables & Power Supplies

Adapters, Cables & Power Supplies

Ocean Insight offers accessories for your electronic and power supply needs. Interface cables and power supplies are available for spectrometers and light sources, plus a breakout box for triggering and more.

Interchangeable Slits

Interchangeable spectrometer slits -- round SMA aperture-slit assemblies -- are available for most Ocean Insight spectrometers. Slits can be purchased individually or as a kit, in diameters from 5 µm to 200 µm.
