Review THORLABS Bandpass Filter Cwl 980 Nm Fwhm Optics

The Thorlabs FB980-10 bandpass filter is an essential optics component designed for use in applications requiring precise wavelength selection in the near-infrared region. This filter is specifically tailored to transmit light at a central wavelength of 980 nm, making it an excellent choice for applications such as biomedical research, laser systems, and optical communications.

The FB980-10 bandpass filter is characterized by a narrow 10 nm full width at half maximum (FWHM) spectral bandwidth. This narrow bandpass enables effective rejection of unwanted wavelengths, reducing the amount of stray light and enhancing the signal-to-noise ratio. The filter's high transmission efficiency, combined with its low reflection and low absorption, allows for efficient and effective wavelength selection in various optical setups.

This filter is constructed from high-quality, durable materials, ensuring reliable performance and long-lasting use in demanding applications. The filter's optical surface is anti-reflection coated on both sides to minimize reflections and maximize transmission. Additionally, the filter's optical face is flat to within 2 lambda ( ) of the design specification, ensuring compatibility with various optical components and systems.

The FB980-10 bandpass filter is available in several sizes, including 25.4 mm x 25.4 mm, 30 mm x 30 mm, and 50.8 mm x 50.8 mm, to accommodate a wide range of optical applications. The filter's robust design, combined with its high transmission efficiency and narrow bandpass, makes it an indispensable tool for researchers, engineers, and scientists working in the field of near-infrared optics and spectroscopy.

The Thorlabs FB980-10 bandpass filter is designed for use in applications requiring wavelength selection at 980 nm with a relatively wide bandwidth of 10 nm full width at half maximum (FWHM). Here are some potential pros and cons of purchasing this filter:

1. Wide transmission bandwidth: The 10 nm FWHM bandwidth of the FB980-10 filter is suitable for many applications that require wavelength selection but do not require extreme spectral resolution.

2. High transmission efficiency: The filter has a typical transmission efficiency of 80% at the center wavelength, which is relatively high for a bandpass filter with such a wide bandwidth.

3. Low wavelength dependence: The filter has a low wavelength dependence, which means that the transmission bandwidth remains relatively constant over a wide temperature range.

4. Durable construction: The filter is made of high-quality optical materials and is designed for robust use in laboratory environments.

5. Available in various mounting options: The filter is available in various mounting options, including threaded, L-shaped, and square mounts, making it versatile for use in different applications.

1. Limited wavelength selectivity: The relatively wide bandwidth of the filter means that it may not be suitable for applications that require very high spectral resolution or wavelength discrimination.

2. Potential for reflections: The filter has a relatively high reflectivity at wavelengths outside the transmission bandwidth, which could potentially cause unwanted reflections and interference in sensitive applications.

3. Potential for absorption losses: The filter may have some absorption losses, which could reduce the overall throughput of the system.

4. Cost: The filter may be more expensive than other filters with narrower bandwidths or lower transmission efficiencies.

In conclusion, the Thorlabs FB980-10 bandpass filter is a robust and versatile option for applications that require wavelength selection at 980 nm with a relatively wide bandwidth. Its high transmission efficiency, low wavelength dependence, and durable construction make it a good choice for many laboratory applications. However, its relatively wide bandwidth may limit its suitability for applications that require high spectral resolution or wavelength discrimination. Additionally, its potential for reflections and absorption losses, as well as its cost, may be drawbacks for some users. Ultimately, the decision to purchase the FB980-10 filter will depend on the specific requirements of the application and the trade-offs between wavelength selection, transmission efficiency, cost, and other factors.

If the application requires wavelength selection at 980 nm with a relatively wide bandwidth and high transmission efficiency, the Thorlabs FB980-10 bandpass filter is a good choice. However, if the application requires high spectral resolution or wavelength discrimination, a narrower bandpass filter or other wavelength selection method may be more appropriate. Additionally, it is important to consider the potential for reflections and absorption losses and the cost of the filter in relation to the overall system requirements and budget.

Transmission Direction Engraved on Edge Transmission Only Affects Back scatter and Reflection, Not Filter Performance. Wave lengths from 700 nm to 2000. Features: Excellent Suppression in Rejection Rejoinders > 4 CWL 2000 nm. These filters can be mounted in our extensive line of.

Dabs > 5 Cowls 700 to 1650 nm. Custom Bandpass Filter Sizes are Available by Contacting. Hard-Coated Bandpass Filter Kits Sold Below. The wave length and pass bands for these filters are specified light normally incident on the surface.

These bandpass filters feature durable, hard-coated dielectric coatings on a UV fused silica substrate. 12.5mm and 25 Outer Diameters Available. This coating can withstand the normal cleaning and handling necessary when using any high-quality optical component. The dense coating on these filters allows them to be constructed using a single substrate, which yields stable, long-lasting filter.

Please see the Comparison tab for information about advantages of hard-coated filters compared to soft-coated filters, such as increased durability and transmission performance. Each filter is housed in a black anodized aluminum ring that labeled with an arrow indicating the design propagation direction. The ring makes handling easier and enhances the blocking OD by limiting scattering.
