Review THORLABS INC Ne20ab New In Box

The Thorlabs NE20A-B (NE20AB) is a versatile and compact NIR-visible laser combiner box designed for assembling and aligning multiple laser beams into a single collimated beam. This device is ideal for applications that require the combination of multiple laser sources, such as confocal microscopy, spectroscopy, or multispectral imaging systems.

The NE20AB box is constructed with a rugged anodized aluminum housing, ensuring durability and stability in various laboratory environments. It features a large beam entrance window made of ZnSe, providing excellent transmission in the near-infrared (NIR) range from approximately 600 to 1100 nm. The window can be optionally coated with an antireflection (AR) coating for enhanced transmission and reduced stray light.

The NE20AB is designed to accommodate up to five laser inputs, each with an independent adjustable attenuator. These attenuators enable precise control of the power levels of individual laser beams, ensuring optimal beam combination and minimizing the risk of damage to sensitive components. The attenuators are also equipped with locking screws to prevent accidental adjustments during operation.

The laser beams are combined inside the NE20AB using a set of adjustable dichroic mirrors. These mirrors are designed to efficiently reflect NIR wavelengths while transmitting visible light, ensuring minimal loss and interference between the beams. The mirrors can be manually adjusted using a set of knobs, allowing for precise alignment and optimization of the beam combination.

The output beam from the NE20AB is collimated using an adjustable focusing lens. This lens can be adjusted to ensure that the combined beam is collimated and has the desired beam size and shape. The NE20AB also includes a set of adjustable irises to control the beam diameter and minimize stray light.

The NE20AB is designed to be easily integrated into various laboratory setups, with standard SMA and FC/PC connectors for the laser inputs and outputs. It also features a removable base plate, allowing for easy mounting and positioning of the device.

Overall, the Thorlabs NE20A-B (NE20AB) is a high-performance and versatile laser combiner box, offering precise control and efficient beam combination for various NIR-visible laser applications. Its rugged construction, adjustable components, and easy integration make it an essential tool for researchers and laboratory professionals.

The Thorlabs NE20A-B (or NE20AB) is a compact, versatile and powerful 20 mW diode-pumped solid-state (DPSS) laser system. It is widely used in various applications such as material processing, spectroscopy, and scientific research. In this response, we will discuss the pros and cons of buying a NE20A-B laser system to help you make an informed decision.

1. Powerful: The NE20A-B laser system delivers 20 mW of continuous-wave (CW) output power which is sufficient for many applications.

2. Compact: The laser system is compact in size, making it easy to transport and integrate into various experimental setups.

3. Versatile: The NE20A-B laser system can be used with a wide range of applications due to its tunability from 532 nm to 561 nm.

4. Stable: The laser system has a stable output power and wavelength over time, making it ideal for precise measurements and experiments.

5. Easy to use: The laser system is user-friendly and requires minimal maintenance.

1. Expensive: The NE20A-B laser system is relatively expensive compared to other laser systems with similar power output.

2. Limited Tuning Range: While the NE20A-B laser system has a wide tuning range, it may not be sufficient for some applications that require specific wavelengths.

3. Noise: The laser system can produce some noise during operation, which may interfere with sensitive measurements or experiments.

The Thorlabs NE20A-B laser system is a powerful, compact, versatile, and stable laser system that is widely used in various applications. However, it is relatively expensive and may not have a wide enough tuning range for some applications. The decision to buy the NE20A-B laser system depends on the specific requirements of your application, budget, and the availability of alternative laser systems that may meet your needs.

If you require a powerful, compact, and versatile laser system with a stable output power and wavelength, and have the budget for it, the Thorlabs NE20A-B laser system is an excellent choice. However, if you have a limited budget or require a laser system with a wider tuning range, you may want to consider alternative laser systems with similar specifications. It's always recommended to consult with a laser expert or supplier to help you make the best decision based on your specific requirements and budget.
