Wide Angle Lens – M300617513730

M300617513730 is 0.6mm 1/7.5″ Wide angle Fixed Focal lens with 137° FOV, M3.8×0.15 mount F3.0 Aperture Suitable for security Surveillance.

0.6mm Ultra Wide Angle M3.8 Miniature Lens

This 0.6mm ultra wide angle miniature lens is designed for compact imaging systems using 1/7.5″ sensors, providing a 137° diagonal field of view in an extremely small optical package. With an F3.0 aperture, 0.3 Megapixel resolution, fixed focus, and M3.8×0.15 mounting thread, it is well suited to embedded vision devices where a very wide viewing area is required within limited installation space.

The lens provides 108° horizontal and vertical FOV, making it suitable for applications that need broad scene coverage from a short working distance while maintaining a compact mechanical footprint.

0.6mm Ultra Wide Angle Lens Applications

Ultra-Wide Coverage for Compact Imaging

The 0.6mm focal length provides a much wider viewing angle than conventional miniature lenses, making this lens suitable for systems where the camera must observe a large scene from a very limited installation position. The 137° diagonal FOV and 108° horizontal/vertical FOV can help increase scene coverage without requiring a physically larger optical assembly.

Because the lens is designed for a 1/7.5″ image format, it is intended for very small image sensors rather than larger industrial camera sensors. The 0.3 Megapixel resolution also makes it more appropriate for applications where wide-area visual coverage and compact integration are more important than high-resolution image detail.

For engineers developing miniature camera modules, the lens can be evaluated alongside other compact optical solutions through TOWIN’s M8/M7/M6 miniature lens range.

Compact Embedded Vision Systems

The M3.8×0.15 mounting thread and 0.875mm F.B.L. are particularly relevant to small camera assemblies where available mechanical space is restricted. The lens can be integrated into compact vision modules, embedded cameras, monitoring devices, and other miniature imaging equipment requiring a broad viewing area.

Its manual focus and fixed iris simplify the optical configuration, making it suitable for applications with a predefined installation distance and stable operating conditions.

Ultra-Wide Field of View for Small Sensors

A key characteristic of this lens is the combination of a 0.6mm focal length and 137° diagonal FOV. This configuration enables a small 1/7.5″ sensor to capture a broad scene from a compact camera position.

The 108° horizontal and 108° vertical FOV are particularly useful when the camera needs to cover a large surrounding area rather than produce a narrow, detailed image. Engineers selecting a lens for a specific camera geometry can use TOWIN’s FOV Calculator to evaluate field-of-view requirements against sensor and installation parameters.

The lens should be considered an ultra-wide-angle lens rather than a fisheye lens. Although its FOV reaches 137°, its classification is based on the intended optical design and application rather than FOV alone.

Compact M3.8 Mechanical Configuration

The M3.8×0.15 mount provides a smaller mechanical interface than conventional M12, C-Mount, or CS-Mount lenses. This makes the lens particularly relevant to miniature camera designs where the lens barrel and mounting footprint must be minimized.

With an F.B.L. of only 0.875mm and a C.R.A. below 30°, system designers should verify the sensor package, chief-ray-angle compatibility, mechanical stack-up, and available back focal space before mass production.

Distortion Considerations

The specified distortion is less than -34%, which reflects the strong wide-angle optical geometry required to achieve the 137° diagonal field of view. Therefore, this lens should not be positioned as a low-distortion lens.

For systems where geometric accuracy is critical, engineers should consider whether software correction or an alternative optical design is required. TOWIN’s Distortion Guide provides additional information about distortion characteristics and their impact on imaging systems.

The high FOV-to-size ratio can nevertheless be valuable when the primary requirement is maximum scene coverage within a very small optical package.

Frequently Asked Questions

Q: What sensor size is this 0.6mm lens designed for?
A: This lens is designed for a 1/7.5″ image format and is intended for very small image sensors.

Q: What is the field of view of this 0.6mm miniature lens?
A: The lens provides a 137° diagonal FOV, with 108° horizontal and 108° vertical FOV.

Q: Is this 0.6mm lens a fisheye lens?
A: No. Although it provides a very wide 137° diagonal FOV, this product is classified as an ultra-wide-angle lens rather than a fisheye lens.

Q: What is the distortion specification?
A: The specified distortion is less than -34%. Therefore, it is designed for wide-angle coverage rather than low-distortion imaging.

Q: What type of mount does this lens use?
A: The lens uses an M3.8×0.15 miniature mounting thread.

Q: Is the aperture adjustable?
A: No. The lens uses a fixed F3.0 aperture.

Q: Does the lens have an IR-cut filter?
A: No. The structure is specified as Without IRCF. This means the lens itself does not include an IR-cut filter; it should not be interpreted as an IR-corrected optical design.

Q: What applications are suitable for this lens?
A: It fits compact embedded cameras, miniature vision modules, wide‑area monitoring devices, small machine‑vision systems, and other applications that demand broad scene coverage within a highly compact form factor.
