Workings of a Crossed Czerny-Turner Spectrometer:
Detector
As the dispersed light strikes the detector’s pixels, the electronics digitize the data to be displayed
Each pixel represents a portion of the spectrum and as the incident light strikes the individual pixels across the CCD, the electronics can then translate and display their intensity using our software, BWSpec™.
The quantum efficiency (QE), dynamic range (DR), and noise level of the array detector largely dictates the spectrometer sensitivity, dynamic range and signal-to-noise ratio. The spectral acquisition speed of the spectrometer is mainly determined by the detector response over a wavelength region.
6
4Grating
Determines wavelength range and spectral resolution
The groove frequency of the grating determines two key aspects of the spectrometer’s performance: the spectral resolution and the wavelength coverage. The higher the groove frequency, the more resolution the instrument will achieve; however, the wavelength coverage will be less. Inversely, decreasing the groove frequency increases wavelength coverage at the sacrifice of spectral resolution. With over twenty-five gratings to choose from, we can customize your application needs. The blaze angle or blaze wavelength of the grating is also a key parameter in optimizing the spectrometer’s performance. The blaze angle determines the maximum efficiency the grating will have in a specific wavelength region. We have a variety of blaze angles available per groove frequency to match your application needs.
SMA 905:
Precision Fiber CouplerBy coupling the SMA 905 adapter with a fiber or lens, light will be guided to the slit and optically matched. This ensures reproducibility for light coupling from the fiber or lens into the optical bench.
1
Slit
Determines the photon flux and optical resolutionLight entering into a spectrometer’s optical bench via a fiber or lens is focused onto a pre-mounted and aligned slit, which ultimately determines the optical resolution and throughput of the spectrometer after grating selection.
Collimating Mirror
Collimates and redirects the light beam towards the grating3
Focusing Mirror
Refocuses the dispersed light onto the detector
When working in the UV-Vis spectrum, both mirrors are F# matched focusing mirrors coated with AlMg2,which produces approximately 95% reflectance. Aluminum (Al) provides reflectance and Magnesium (Mg2) protects the aluminum from oxidation.
When working in the NIR, both mirrors are F# matched focusing mirrors coated with a special coating that enhances the NIR signal.

Thermoelectric Cooler
Reduces dark noise and increases the dynamic rangeCooling an array detector with a built-in Thermoelectric Cooler (TEC) is an effective way to reduce dark current and noise, as well as to enhance the dynamic range and detection limit. For Si detectors, dark current halves when its temperature is decreased every 5 - 7°C. For InGaAs detectors, dark current halves when its temperature is decreased every 7 - 10°C. This allows the spectrometer to operate at long integration times and detect weak optical signals.

Concave Holographic Grating
Collects, disperses and refocuses lightThis one compact optical component collects, disperses, and refocuses light onto the detector by combining two optical components, i.e. the grating and focusing mirror found in standard optical benches. The optimized holographic grating delivers excellent efficiency and stray-light reduction and is able to provide a faster F#, delivering higher throughput.

Thermoelectric CoolerCooling an array detector with a built-in Thermoelectric Cooler (TEC) is an effective way to reduce dark current and noise, as well as enhance the dynamic range and detection limit.
The graph shows the dark current and noise for an uncooled vs. cooled CCD detector at an integration time of 30 seconds. When operating at room temperature, the dark current nearly saturates the uncooled CCD. When the CCD is cooled down to 14oC by the TEC, the dark current is reduced by four times and the dark shot noise is reduced by two times. This allows the spectrometer to operate at long integration times and detect weak optical signals.

Thermoelectric Cooler
Cooling an array detector with a built-in thermoelectric cooler (TEC) is an effective way to reduce dark current and noise as well as enhance the dynamic range and detection limit.
When the InGaAs detector array is cooled down to 5oC by the TEC from a room temperature of 25oC, the dark current is reduced by 6.25 times and the dark noise is reduced by a factor of 2.5. This allows the spectrometer to operate at longer exposure times and detect weaker optical signals.

Fiber Patch Cords
BFA & BRS Bifurcated Fibers
Fiber Dip Probe
The Fiber Patch Cords (FPC) series are fiber optic cables terminated with fiber optic connectors on both ends and are available in single strand UV or NIR grade fused silica optical fiber with various core diameters for use in the spectral range 190nm - 2400nm.
Fiber core sizes range from 50um to 1000um. Standard lengths are 1.5 meters with custom available.
The Bifurcated Fiber Assembly (BFA) series combines optical fibers at a common end with the fiber bundle bifurcated into two separate channels. These channels can connect to a light source and a spectrometer or split an incoming signal into two separate spectrometer channels. When a collimating lens is attached to the common end of the assembly and positioned correctly, the specular reflectance for 0° angle of incidence can also be measured.
The fiber dip probe (FDP) series can be used for measuring the transmittance and absorbance of liquid solutions. The fiber dip probe can be inserted into liquids for in-situ %T/Abs measurements. Typical applications include observing changes in solutions for kinetic reaction studies or dissolution testing.
Fiber Reflectance Probe
The Fiber Reflectance Probe (FRP) series combines 7 optical fibers at the sample end into a bifurcated fiber. This bifurcated fiber splits into one fiber and 6 stacked fibers with the single fiber connecting to a light source and the 6 stacked fibers connecting to a spectrometer. These stacked fibers align to the spectrometer’s slit for increased signal input. When properly setup, the FRP can measure diffuse or specular reflectance from surfaces.

Two SMA 905 fiber couplers with collimated optics come with the BCH100A and three come with the BCH103. Both can be used with any B&W Tek, Inc. fiber, array spectrometer and BPS or BDS light sources. The BCH100A comes with two straight through SMA 905 ports. The BCH103A can be used for fluorescence when setup for right angle measurements with respect to illumination.
The BIP2.0 is a compact, fiber coupled integrating sphere with an integrated 20W tungsten halogen lamp which emits over the UV-NIR Spectrum. The two inch diameter integrating sphere is machined from PTFE, which is highly reflective (99% from 400-800nm), and Lambertian, over the broad spectral range of 250-2500nm.
The BIP2.0 incorporates a fan for thermal stability for low drift and operates on 12 V DC. It is designed for measuring diffused reflectance using any B&W Tek, Inc. array spectrometer.
