FL-400 fire-resistant fiber optic probe
; High-temperature fiber; The FL-400 flame-retardant fiber optic probe includes an 8-inch-long nickel sleeve, inside which is placed a 400µm high-temperature-resistant UV-VIS fiber, and the fiber's protective layer is a gold-plated surface. The probe is connected through a coupling sleeve to a standard SMA-interface fiber, and the fiber is connected to a spectrometer to measure the radiation spectrum.; Spectrometer teaching tool; The FL-400 fire-resistant fiber optic probe is particularly suitable for radiation measurement with CHEM4 series spectrometers (low-cost UV-VIS spectrometers for laboratory teaching), serving as a teaching tool for spectrometers. It can be used mainly in two ways:; Insert it into a radiating sample environment up to a maximum of 750 degrees Celsius; By adding a standard platinum or nickel coil at the head of the probe to measure the radiation spectrum of the flame of experimental substances, such as sodium, potassium, calcium, copper, etc.; Related experiments used to understand radiation measurement; Specifications; The following specifications apply to the probe composed of a gold-plated protective-layer fiber and a nickel sleeve.; Components; The probe, fiber, and coupling sleeve can be purchased as a set or separately.

CC-3 cosine corrector for radiant light collection
Fiber Probes
Gzbiaoqi
Diffusing material: Milky white glass Wavelength Range: 350-1000 nm Dimensions: 6.35 mm OD
Optional probe When the CC-3 and CC-3-UV are mounted at the end of a fiber, the cosine corrector and the fiber form a radiation probe. This probe is connected to an Ocean Optics spectrometer to measure the radiant intensity of light at the probe's surface. Direct connection CC-3-DA can be connected directly to the SMA 905 connector of the USB2000, HR4000, or S2000 spectrometer, forming a complete spectrometer system without a connecting cable, with no need for a fiber. Diffusing material: UV-VIS or VIS-NIR The diffusing material of the cosine corrector can be a milky-white, thin glass disk ((350-1100 nm) or Spectralon (200-1100 nm), located at the end of the stainless steel sleeve.

Attenuated Total Reflectance Probe (PRO-PROBE-ATR)
Fiber Probes
Gzbiaoqi
Outer Diameter: 12.7 mm (0.5"), optionally 12 mm (0.47") Probe length: ~305 mm Body Material: 316 stainless steel (Hastelloy C, titanium, and Monel alloy also available)
The ATR probe is the ideal product for measuring samples with absorbance of 4000-5000 AU/cm. It can be inserted directly into the sample to obtain a spectrum without diluting the sample. In addition, if the refractive index of the deposit material at the probe tip is greater than the refractive index of the sapphire crystal of the ATR probe, or greater than 1.7, the ATR probe can be used as a general-purpose probe.
