Laser Diodes for Raman Spectroscopy

Laser Diodes for Raman Spectroscopy

These lasers are diffraction limited and can focus to micron size spots, unlike the higher power lasers, which at best can focus to a 100 micron spot size.
Technology From: Micro Laser Systems

Laser Diodes for Raman Spectroscopy

Power Output: 28mW-490mW
Wavelengths: 405nm-785nm

For many Raman spectroscopy applications, about 100mW in a small beam is all that is required. To date this has only been satisfied by higher power (300-500mW) multimode lasers with line widths of 0.5nm or larger.

These lasers are designed to give diffraction limited output with narrow line width and high stability. Because they are diffraction limited, they can focus to micron size spots, unlike the higher power lasers, which at best can focus to a 100 micron spot size. These lasers are based on the Lepton IV Series and offer a very affordable alternative to the high power lasers for Raman. This makes these lasers ideal for Raman microscopy.

For OEM

Original Equipment Manufacturer
systems, the laser has a very small body with ample mounting holes. Most lasers for Raman have a much larger body and higher power requirements. Output is a ∼2mm circular, Gaussian beam with options for a 4mm or 6mm for Raman confocal microscopy. They also last much longer, operate at lower power and can be pulsed for certain applications.

These lasers make an excellent source for confocal microscopes, scanning, optical tweezers, ophthalmetry, tissue analysis and more.

Key Features
  • 785nm 95mW, 785nm 490mW,
  • 660nm 28mW
  • 2mm circular Gaussian beam

Technology From: Micro Laser Systems

Micron Spots with Long Working Distance

Power Output: 100mW or more
Wavelengths: 375nm-1600nm

In many applications, such as in fluorescence excitation, printing, photo plotting, detector pixel analysis, small micron size spots need to be generated with long working distance.

Warsash Scientific offer a series of lenses that when combined with the Lepton IV Series of diode lasers, generate micron size spots with long working distance. The optics are integrated onto the Lepton IV housing making a small compact package. Output powers of the Lepton IV Series are 100mW or more at various wavelengths which are then focused to a 1 to 10 micron spot size. This yields very high power densities at the focused spot. This means you will get higher signal to ratios.

Zpol

Zpol

The ZPOL turns the linear polarised light to radial polarised light.
Technology From: Micro Laser Systems

Zpol

Wavelengths: Specify at time of order

ZPOL is a device to generate radial polarisation, which when combined with a high numerical lens, generates polarisation in the Z direction.

Linearly polarised light is incident on the ZPOL. It can be used in conjunction with the Lepton IV Series. The ZPOL turns the linear polarised light to radial polarised light. Next a high NA lens is used. As the light is being focused the X and Y components cancel out at the focus leaving only the z component, or Z polarisation.

Key Features
  • Radial polariser
  • Polarises light in the direction of propagation with focusing optics
  • Obtain 3D orientation of molecules and crystals

Speckle Reducer

Speckle Reducer

This Speckle Reducer was developed to decrease the coherence of the laser.
Technology From: Micro Laser Systems

Speckle Reducer

Wavelengths: 450nm-950nm

When a laser illuminates an object, speckle noise appears and degrades your image. This Speckle Reducer was developed to decrease the coherence of the laser.

The Speckle Reducer uses different lengths of optical fibre, where each fibre differs more than the coherence length of the source. It has no moving parts and there is no vibration noise. This is excellent for temporal resolved imaging.

The Speckle Reducer also works as a beam homogeniser. The input Gaussian intensity profile is transformed into a homogeneous profile.

Key Features
  • Reduces laser speckle noise and improves image quality
  • Beam homogeniser
  • No moving parts
  • Totally passive
