Our 3D glasses are so inexpensive, you can outfit your family and friends for a fraction of the cost of other 3D technologies.Our glasses work in Real D 3D and Disney Digital 3D theatres with Stereo Graphics Z-screens and with the new JVC GD-463D10 monitors. Note: Will not work in Imax 3D Theatres.Take your own 3D Glasses to the Movies!! Our glasses work in Real D 3D and Disney Digital 3D theatres. In a movie theater, the reason why you wear 3D glasses is to feed and separate two different images into your eyes. Two projectors are synchronized and project two respective views. The screen actually displays the two images, and the glasses cause one of the images to enter one eye and the other image to enter the other eye.Sturdy plastic frames are mounted with specially made circular polarized lenses. Polarizing efficiency = 99.8%; Transmittance = 43.7%. Ultra-violet filtering to 380. Surface hard coating to 3HYou can choose your Frame-Color from the drop down menu above. Frame color will default to the frame color in drop down window.*Minimum order for Circular Polarized 3D glasses is 2 pieces at $4.75 each

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.

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.

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.

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.

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.

Firebird provides a range of sizes and shapes both coated and uncoated though if you do not see your desired silicon lens please contact us and we can quote for a custom lens.

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.

Low Dispersion: Silicon exhibits low dispersion properties, meaning it effectively minimizes chromatic aberrations in optical systems. This feature ensures better image quality and reduced color fringing effects, particularly beneficial for imaging applications.

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.

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.

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.
