Ideal Spectroscopy Optical Arm Assembly, For Coupling Laser Light Into A Chamber, CF 2.75 Inch Conflat FlangedWith Windows at Brewster’s Angle 56°, Rotatable Mount With Viton Seals. Our Ideal Spectroscopy optical arm assemblies are precision-engineered for superior light control. Unlock the full potential of your spectroscopy and optical experiments, they are designed to optimize laser light interaction within vacuum chambers while minimizing unwanted background noise, greatly eliminating the laser scatter that is generated when the beam passes through the exit window. Spectroscopy relies on the interaction of light with matter, where light can be absorbed, reflected, or scattered by a medium. To achieve precise measurements, it is essential to efficiently guide an intense laser beam into the experimental vessel while reducing the background noise caused by laser light scattering off the inside of the chamber that can overwhelm the optical detector. Our optical arms are engineered to enhance the signal-to-noise ratio, ensuring maximum fluorescence, phosphorescence, and Raman scattering detection while minimizing stray light interference.Key FeaturesOptimized for Spectroscopy: Designed to enhance signal collection for applications such as: Laser-Induced Fluorescence (LIF) Emission Spectroscopy Raman Spectroscopy Coherent Anti-Stokes Raman (CARS) Laser-Induced Breakdown Spectroscopy (LIBS) And more Precision Vacuum Compatibility: Equipped with a standard 2.75” ConFlat flange, allowing seamless integration with vacuum chambers and vessels. High-Efficiency Optical Window: Includes a vacuum window mounted at Brewster’s angle, maximizing the transmission of p-polarized light and reducing reflection losses. Optional Advanced Light Baffle Kit: For further reduction of laser light scattering, an optional baffle kit can be inserted, ensuring even greater optical clarity. Durable and Modular Design: Crafted from black anodized aluminum for durability and compatibility with Ideal Vacuum Cubes, enabling quick and flexible experimental configurations. Whether conducting fluorescence spectroscopy, Raman analysis, or advanced laser-based experiments, our Ideal Spectroscopy Optical Arm provides superior performance, ease of installation, and precision-engineered optical optimization. In addition, there are various manufacturing and scientific research applications where laser light is used to excite or observe an effect in a material under desirable conditions of low laser scattering, which can benefit from our Ideal Spectroscopy Optical Arm assemblies. Here are a few notable methods:Laser-Induced Breakdown Processing (LIBP) Used in material processing and micro-machining. A high-intensity laser pulse excites a material, leading to plasma formation that alters the surface or internal structure. The key effect is the modification of the material, not laser scattering from the surrounding environment. Laser Heating & Thermomechanical Studies Lasers can be used to heat a small, specific area of a material with minimal scattering. Used in thin-film deposition, annealing, and thermal conductivity studies. The effect observed is the change in material properties rather than scattered light. Optical Tweezers & Laser Manipulation Highly focused laser beams trap and manipulate microscopic particles without direct scattering from containment walls. Used in cell biology, colloidal physics, and materials science. The key effect is the controlled movement and force application on the target, rather than light scattering. Laser-Induced Phase Transitions Used in materials research and condensed matter physics. A laser pulse can trigger phase changes (e.g., melting, crystallization, amorphization). Observations focus on phase transformation dynamics rather than scattered laser light. Photoacoustic & Photothermal Microscopy A pulsed laser excites a material, generating heat or pressure waves that propagate and are detected acoustically or thermally. Used in biomedical imaging, materials testing, and non-destructive evaluation. The observed effect is a mechanical or thermal response rather than scattered light. Laser-Induced Electron Emission & Photoemission Microscopy Ultrafast lasers excite electrons in a material, causing them to be emitted. Used in surface science and semiconductor research. The key observation is the emitted electrons, not the scattered laser beam. Laser-Assisted Chemical Reactions Lasers initiate or accelerate chemical reactions in a controlled manner. Applied in photopolymerization, thin-film growth, and plasma-enhanced chemical vapor deposition (PECVD). The focus is on chemical changes rather than light scattering. Warning: Vacuum Cube Plates with CF-style ports are not compatible with copper gaskets! Use only Viton gaskets to prevent damage to the plate sealing surface.These products are made of aluminum, a softer material than copper, and will be damaged if standard UHV copper gaskets are used. Our Ideal Vacuum Cube products and Ideal Spectroscopy Optical Arms are designed for quick and easy use in the HV region, from atmosphere to 10-8 Torr. These products contain O-rings and are not compatible with UHV conditions. Selected Research Publications - Where Data Was Collected Using Our Ideal Spectroscopy Optical Arm Assemblies: 1.
