Raman spectrometers
Need fast, sensitive Raman? Wasatch Photonics line of high throughput modular Raman spectrometers deliver the best price to performance on the market, from the visible through NIR. Designed with our proprietary volume phase holographic grating in an f/1.3 bench, these spectrometers allow you to capture and keep more photons to achieve better SNR at the sample. This translates into lower limits of detection for applications like SERS, and enables higher data collection rates for kinetics monitoring and quality control on ultra-high speed production lines.

We believe you should have full control and maximum flexibility when configuring your 248 Raman spectrometer. That’s why we offer several build-to-print options for resolution, detector cooling, and sample coupling – backing each with our advice and experience. Learn more about each below, or contact us to discuss the best options for your application.
SLIT WIDTH: Defining Resolution
Sensitivity and resolution are competing factors when choosing slit size. A larger slit allows more light to enter the spectrometer, increasing sensitivity for low-light applications such as fluorescence. Resolution improves, however, as slit width is reduced (though not always linearly). We offer a 25 μm slit as standard for the WP 248 for the best balance between sensitivity and resolution for most applications. Please contact us if you feel a different slit size would be best suited to your research.
SAMPLE COUPLING: Integrated lens or free-space?
How you interface with your Raman sample depends on your preferred sampling optics. The standard configuration for the WP 248 Raman spectrometer features an integrated lens designed to efficiently couple collimated light into the f/2.0 spectrometer input. We also offer a free-space input to collect light from an f/2.0 field-of-view (FOV) upon request. The two coupling options are user-exchangeable in the field.

We believe you should have full control and maximum flexibility when configuring your WP Raman spectrometer. That’s why we offer so many build-to-print options for range, resolution, detector cooling, and sample coupling – backing each with our advice and experience. Learn more about each below, or contact us to discuss the best options for your application.
SLIT WIDTH: Defining Resolution
Sensitivity and resolution are competing factors when choosing slit size. A larger slit allows more light to enter the spectrometer, increasing sensitivity for low-light applications such as fluorescence. Resolution improves, however, as slit width is reduced (though not always linearly). We offer 10, 25, and 50 μm slits for many of our spectrometers, and can advise on the best choice for your application. Due to the high sensitivity of our low f/# spectrometer designs, it is often possible to use a smaller slit width than would be required with a typical f/4 spectrometer, allowing you to achieve higher resolution.
SAMPLE COUPLING: Fiber, free-space, or integrated laser?
How you interface with your Raman sample depends not only on whether you value convenience or configurability, but also on the data quality you require. See below for some quick tips, or reach our sample coupling tech note to learn how to get more out of our many sample coupling & configuration options.
Fiber coupled spectrometer & probe
Our f/1.3 design delivers superior signal and ultra low background when used with our matched NA probes. Simplifies sample alignment in the lab or field.
Free-space coupling to spectrometer
This 0.36 NA input offers superior signal & freedom in the design of your own sampling optics, from spot size to working distance. Ideal for research & OEMs.
Integrated laser & free-space coupling
Our compact design integrates laser control and optimized coupling optics for best signal to noise. For turnkey lab use & OEM integration.
DETECTOR COOLING: Controlling noise
We offer ambient, regulated, and TEC cooled detectors, allowing you to balance your required signal to noise ratio (SNR) and temperature stability with cost for the best possible value.
An uncooled detector is often adequate for many basic spectroscopy applications, but for lowest limit of detection and long term measurements, a thermoelectrically cooled (TEC) detector delivers unparalleled performance. Contact us to discuss the right choice for your application.
