In the realm of miniature electronics, every fraction of a millimeter and every photon counts. The housing for a sensitive optical component is not just a shell; it is the first line of defense and the final gateway for the signal. Imagine a delicate photodiode, engineered to detect minute light fluctuations, being encased behind a curved surface. That curve, however slight, acts like an uncontrolled lens, bending and scattering incoming light, blurring the signal before it even has a chance to be processed. This is the fundamental challenge our TO-33 Flat Window Cap Shell is designed to eliminate. It is a testament to the principle that true precision begins with an unobstructed view.
Feel the clarity in your design. The window is impeccably flat, polished to an optical grade that feels smooth and cool to the touch. It presents a pristine, planar surface to the world, allowing light to travel in a straight, unaltered path directly to the sensor within. This deliberate choice eradicates the optical aberrations and focal shifts caused by traditional domed caps, ensuring that the signal your device receives is a pure, accurate reflection of reality. Surrounding this crystal-clear portal is the steadfast strength of a Kovar alloy body. It feels solid, meticulously engineered, and dependable. Its unique composition is chosen for one critical reason: it expands and contracts in perfect harmony with the sealing glass during the intense heat of the sealing process and the thermal cycles of operation. This synergy creates a hermetic sanctuary—a fortress that locks performance in and keeps the harsh external world out.
This component was born from a story of demanding absolute perfection. It’s for the engineer designing a life-critical medical monitor where accuracy is non-negotiable. It’s for the innovator creating a compact LIDAR system for autonomous navigation, where every scattered photon can mean the difference between a clear path and an obstacle. By choosing our TO-33 Flat Window Cap Shell, you are not just sourcing a part; you are investing in a foundation of unparalleled clarity, reliability, and precision. You are ensuring your most critical innovations are seen in their truest form, protected by a seal engineered to last.

Q1: Can the flat window be coated with an anti-reflection (AR) coating for specific wavelengths?
Yes, we offer custom AR coating services tailored to your application’s needs. We can apply high-performance coatings optimized for various wavelength ranges, including visible, near-infrared (NIR), and short-wave infrared (SWIR), to significantly reduce surface reflections and maximize light throughput.
Q2: What is the guaranteed hermeticity level of the sealed package?
Our standard sealing process produces a hermetic seal that reliably meets or exceeds the requirements of MIL-STD-883, Test Method 1014. We can consistently achieve a leak rate of less than 1 x 10⁻⁸ atm-cc/sec, making it suitable for the most demanding high-reliability applications.
Q3: Do you provide samples for prototyping and evaluation purposes?
Absolutely. We strongly support the prototyping and design verification phase. Please contact our sales department with your project details, and we will be happy to arrange for samples to be sent for your evaluation.
Q4: What is the primary advantage of a TO-33 flat window over a standard curved cap?
The primary advantage is optical accuracy. A curved cap refracts light, acting like an uncontrolled lens that can distort the signal and reduce measurement precision. A flat window provides a direct, non-distorting path for light, which is critical for applications requiring high signal-to-noise ratios, precise light measurement, and accurate beam shaping.
Q5: What are the typical lead times for standard and customized orders?
For our standard TO-33 Flat Window Cap Shell, lead times are generally in the range of 4-6 weeks. For orders requiring customization, such as special coatings or design modifications, a specific lead time will be provided after a thorough review of your technical requirements. We prioritize clear communication and on-time delivery.
