Espectrómetros Raman - 830 nm

830nm laser excitation is a common wavelength chosen for Raman spectroscopy because it has great fluorescence suppression and good scattering efficiency.

-Raman-HR-TEC-830 Spectrometers: are our most popular Raman spectrometers and include an enhanced CCD array detector tuned for 830nm Raman with advanced detector lens assembly for ultra sensitivity at long exposure times.

-Raman-HR-TEC-X2-830 Spectrometers: offers 2-stage detector cooling for ultimate sensitivity and performance! Great for long exposures up to 8 minutes.

-Raman-SR spectrometers: are typically recommended for OEM and portable applications where the specific sample set is known and works well without detector cooling.

Interchangeable Slits Upgrades: are available for “HR” optical benches to allow more application flexibility.  High Scattering samples can be measured with the smallest slit for highest resolution and weak Raman can be measure with a larger slit to allow for increased light throughput.

Raman-Probe-830: Attaches to 830nm laser via FC/APC and spectrometer via SMA 905, has integrated Raman filters and optics (working distance– 4.5mm), high efficiency collection fibers for StellarNet Raman spectrometers

Raman-Probe-TIP: attachements tips can be purchased for additional working distance options. Just screw on to replace

Raman-Probe-TIP-Tele: Telescoping Raman probe tip lens assembly attachment for 3cm working distance. Designed to by mounted on to standard Raman probe with 5mm working distance

RPH4: Raman Probe Holder block supports 1/2″ vials.

RPH5: Vertical Raman Probe Holder Block for powder and solids. Samples are placed onto a slide and inserted into the measurement chamber of the block. Includes a laser safety interlock which only allows the laser to fire when the probe is securely seated into the holder.

Raman-Probe-HT: High Temperature Raman probe to 200 deg C

Raman-Probe-Immersion: Immersion Raman Probes for 830nm source. Stainless-steel, cylindrical probe head with removable immersion sleeve, overall dimensions 5/8″ (15.8mm) diameter x 8″ (230 mm) length

Raman-Probe-Process: Raman Process Probe for 830nm source. Stainless-steel pressure sleeve specified to 3000 psi and up to 500ºC. Sapphire window and gold seal are resistant to many corrosive chemical environments.
