Firebird Optics’ plano-convex Silicon (Si) lenses are the primary way to focus parallel rays of IR radiation into a single point. These types of lenses are also referred to as positive or converging lenses.

Plano-convexlens

Cost-Effectiveness: Compared to some other IR materials, silicon is relatively cost-effective, making it a practical choice for various applications where budget constraints may be a consideration.

Advantages over Germanium: Silicon lenses offer broader spectral transparency, including UV and visible wavelengths, whereas germanium primarily operates in the mid-infrared range. Additionally, silicon is more cost-effective than germanium, making it a preferred choice for certain applications.

Results: Low energy laser treatment caused a rapid wound healing without scar tissue formation (compared to the high energy laser group) and clinical signs of scar tissue formation (compared to control incisions with the conventional scalpel). During the study period, the laser-induced lesions healed through reparative synthesis of the matrix proteins, which led to filling of the tissue defects. The regenerative processes were similar in the low-energy laser group and in the control incisions. In the high-energy lased tissues, we observed a delayed replacement of the defects by newly formed extracellular matrix proteins.

Silicon plano-convex lenses are essential optical components used in a variety of applications in both visible light and infrared (IR) domains. Silicon is a widely used material in the field of optics due to its unique optical properties and ease of fabrication. In this article, we will explore the advantages and disadvantages of silicon plano-convex lenses, their applications in infrared optics, and how they compare to other IR materials.

Night Vision Devices: Silicon lenses are used in night vision devices that rely on infrared light for enhanced visibility in low-light conditions. These lenses enable efficient light gathering and imaging in the infrared spectrum.

Study design/material and methods: This study evaluated the clinical effects of the Nd:YAG laser used with different energy parameters (low energy: 1.75 W and 20 pps/high energy: 3.0 W and 30 pps) in a duration 20-40 s in rat skin. Control incisions were performed with a scalpel blade. Rat skin incisions were examined over a period of 28 days by clinical photographs as well as by using immunohistochemical techniques in order to find the distribution and the amount of the extracellular matrix fibrillar components, i.e., collagen types I and III.

Broad Spectrum Transparency: Silicon has good transparency across a wide spectrum, from the ultraviolet (UV) to the mid-infrared (approximately 1.1 µm). This characteristic makes silicon plano-convex lenses suitable for applications that require operation in both visible and infrared wavelengths.

IR Spectroscopy: Silicon plano-convex lenses are employed in infrared spectroscopy to analyze the interactions between matter and infrared radiation. Their low dispersion characteristics ensure accurate spectral analysis.

Thermal Imaging: Silicon lenses are commonly used in thermal imaging cameras that operate in the mid-infrared spectrum. They allow for efficient focusing of infrared radiation onto the detector, enabling the creation of detailed thermal images.

Germanium IRLens

Advantages over Zinc Selenide: Silicon has better UV transparency, while zinc selenide excels in the longer mid-infrared range. The choice between these materials depends on the specific spectral requirements of the application.

Conclusions: This study showed a slower wound healing in the high-energy lased tissues. A similar healing in the low-energy lased tissues and in the incisions with the conventional scalpel was observed. The differences in the distribution of matrix proteins during healing and the coagulation of the tissues, which were exposed to low-energy laser treatment, might be the explanation for the minimal scarring, contraction, and pigmentation of the lased tissues as compared to conventional incisions.

Optical lenses are components that focus or disperse a light beam toward or away from specific targets. Lenses are made from materials that are transparent across specific wavelength ranges depending on the application. Optical lenses can be crafted with various properties such as Plano-Convex or Bi-Convex, which focuses light on a point while Plano-Concave and Double-Concave diverges the light beams.

Disadvantages compared to Chalcogenide Glasses: Chalcogenide glasses, such as AMTIR-1, possess extended infrared transparency beyond silicon's range. Silicon lenses are limited to approximately 1.1 µm in the infrared, whereas chalcogenide glasses can operate in the long-wave infrared.
