• Other inspection equipment and devices

Regular plate harmonic beam splitter and ultra-thin harmonic beam splitter are two types. High-energy harmonic beam splitters are similar to dichroic beam splitters. They are designed to separate the fundamental wave and harmonics of a laser. Spectral Optics supplies harmonic beam splitters for Nd:YAG lasers and Ti:sapphire lasers. A single-sided high-energy dichroic coating reflects over 99.5% of the target wavelength while transmitting other wavelengths. For wavelengths longer than the target wavelength, it transmits over 90%, and for wavelengths shorter than the target wavelength, it transmits over 85%. The backside is coated with high-energy AR coating for the transmitted wavelengths. If the beam size is small, less than 3mm, a minimum deviation angle is required, and an ultra-thin beam splitter is necessary.

• Other processing machines

Depending on the application, cube beam splitters may not be suitable, and instead, plate beam splitters are used. For the highest levels of wavefront and power handling, conventional coated plate types such as BK7 or fused silica are excellent choices. Spectral Optics offers various R/T ratios of standard plate beam splitters, all coated with dielectric coatings. These are designed for specific wavelengths and polarizations (S-polarized, P-polarized, or unpolarized), at 45° (or other incident angles). The backside is treated with anti-reflective (AR) coating.

• Other processing machines

Spectral Optics, a division of Spectral Products, has developed and released a completely new and innovative type of high-power laser application, a broadband variable beam splitter/attenuator (VBSA). The VBSA can vary the reflection/transmission (R/T) split ratio over a very wide range of wavelengths from infrared to ultraviolet, specifically from 10.6 µm to 193 nm. The innovative VBSA is available in both uncoated and AR-coated versions and can be used with any laser wavelength and any polarization. The Spectral Optics high-power variable beam splitter/attenuator (VBSA) includes uncoated products for use in extreme high-power laser applications at both the input and output apertures. Due to the innovative new design of the VBSA, the uncoated version can be used up to the bulk laser damage threshold of the internal substrate material. As a result, this very high damage threshold makes it a unique product that can be used for almost all high-power lasers operating from FIR wavelengths to UV.

• Other processing machines

Spectral Optics' TrueSplit is a groundbreaking product in beam splitter technology. Most unpolarized beam splitters use hybrid metal coatings or optical cement that absorbs energy. TrueSplit does not use adhesives with hard dielectric coatings. As a result, it achieves absorption below 3%, P-S polarization performance, and a damage threshold of over 20 J/cm². Furthermore, it can achieve almost any R/T ratio (not just 50/50) and nearly any wavelength. The standard unit has a size of 2 ½ inches x 2 ½ inches with an effective diameter of 5/8 inches, and other sizes can be manufactured.

• Other processing machines

Spectras Optics supplies broadband polarizing beam splitter cubes made from SF2 glass. Since SF2 glass has a high refractive index, the broadband polarizing cube beam splitter can be used for high-performance wideband applications. For low and medium power lasers, up to 1 J/cm².

• Other physicochemical equipment

The cube beam splitter consists of two right-angle prisms coated with a special dielectric coating. The polarizing cube beam splitter divides a laser beam into two orthogonal polarization components or is used to combine them into one beam. It transmits P-polarization and reflects S-polarization at 90°. In low-power applications, the cube is assembled using a transparent refractive index matching adhesive at the junction with two 90° right-angle prisms. It can be used up to 1064nm at 1 J/cm². Please enter from the marked surface. Optical contact cubes offer good beam quality, high damage thresholds, a wide wavelength range, and wavefront accuracy, but they are not mechanically stable due to the fragile nature of the optically contacted interface. The new molecular fusion bonding technology from Spectral Optics permanently bonds without using cement or other materials that degrade coating performance.

• Other processing machines

Produced by Spectral Optics, the cube-shaped beam splitter is used because it has no angular displacement and fewer ghosts than plate beam splitters. It has a dielectric partial reflection coating on the inside. All four sides are coated with anti-reflective (AR) coating for specific wavelengths. Please input collimated, parallel light. The bonded cube beam splitter can be used up to 1064nm at 1J/cm². The new molecular fusion bonding technology from Spectral Optics allows for permanent bonding, creating an optically connected unit. This enables their use in very high energy/high power laser applications. No optical cement or other materials that degrade coating performance are used.

• Other processing machines

An anti-reflective (AR) coating is applied to the surface, and the total internal reflection (TIR) inside the right-angle prism will be the same as that of a 45-degree mirror. Metal mirrors cannot be used at high power due to significant absorption, and dielectric-coated mirrors cannot be used for broadband applications; however, TIR is independent of wavelength, so it can be used within the range of the AR coating.

• Other processing machines

Spectral Optics supplies hybrid laser mirrors with high reflectivity and durability for both wavelengths. They are used for alignment in systems utilizing Nd:YAG at either 0° or 45° incidence, YAG wavelength and its second harmonic, as well as visible wavelength tracer lasers. The dual-wavelength (1064nm & 532nm) YAG laser mirrors have a reflectivity of R > 99.0% for both wavelengths. They also provide tracer laser options for either the HeNe wavelength of 633nm or the diode laser wavelength of 670nm. The reflectivity is > 99.0% at the laser wavelength and > 80.0% at the tracer wavelength. Considerations for damage thresholds for visible and near-infrared wavelengths are the same as for standard mirrors. Please consult us for high-power applications in the ultraviolet range.

• Other processing machines

Spectral Optics' laser mirrors have a reflectivity of over 99.5% for visible and near-infrared wavelengths. Common laser wavelengths include YAG, helium-neon, argon, and diode lasers as standard. The mirrors are suitable for both beam steering and applications within resonators. For wavelengths shorter than 355nm, Spectral Optics carefully develops coating designs, coating materials, and substrates to provide mirrors with low absorption and high damage thresholds at specific wavelengths. Please consult us regarding the required peak power, pulse width, pulse repetition rate, and expected intensity distribution. The reflectivity of over 99.5% applies to wavelengths of 248nm and longer, while for shorter wavelengths, it is over 97%.

• Spectroscopic Analysis Equipment

The Stroker f/2 VNIR spectrometer achieves high throughput despite its compact size.

• UV/visible spectrophotometer

The Stroker f/1.3 Raman Spectrometer series achieves the highest throughput among all miniature spectrometers on the market. The design starts with a high-efficiency HD volume phase holographic grating that provides maximum diffraction efficiency and extremely low stray light. At this f/#, a custom lens design with the correct AR coating is required for excellent image quality and high transmittance. Low-noise electronics that make up the system are used in the back-illuminated silicon array. The final step was to use a high NA fiber power converter to effectively couple all the light sampled from the laser spot into the slit. With this type of signal enhancement, TE cooling of the detector is no longer necessary. The integration time is very short, allowing low-power lasers to be used to obtain high SNR Raman spectra.
