What is OEM and ODM process?

Product Development Process

1. Ascertain Specifications

The first step in the process is to determine the exact specifications required for the product. This could include dimensions, materials, features, and any other relevant information.

2. Determine OEM/ODM Model

Once the specifications are determined, the manufacturer will assess if they have an existing OEM/ODM basic model that can be used. If not, they will proceed with designing a new product from scratch.

3. Optical Design

If the product requires optical components, such as a camera or lens, the manufacturer will design and submit optical performance values for approval.

4. Verify Optical Performance Approval

Once the optical design is complete, the manufacturer will verify the optical performance approval with the client.

5. Mechanism Design

After the optical design is approved, the manufacturer will move on to designing the exterior of the product. They will submit exterior drawings for approval by the client.

6. Verify Exterior Drawings Approval

Once the exterior drawings are approved, the manufacturer will verify the exterior drawings approval with the client.

7. Calculate Estimate and Prepare Sample

With the specifications and designs approved, the manufacturer will calculate an estimate for the project, including the cost of materials, labor, and any other necessary expenses. They will then prepare a sample estimate to present to the client.

8. Fabricate Sample

If the client approves the estimate, the manufacturer will proceed to fabricate a sample of the product for the client to review.

9. Shift to Quantity Production

Once the sample is approved, the manufacturer will shift to quantity production, manufacturing the agreed-upon number of products for the client.

Experience the power and precision of the Thunderbolt 8X36 Military Binocular, a cutting-edge optical instrument designed for ground force and marine army operations. This binocular combines exceptional performance, rugged durability, and advanced features to provide military professionals with a tactical advantage in reconnaissance, surveillance, and target acquisition missions.

Precision Optics for Tactical Superiority

The Thunderbolt 8X36 Military Binocular features advanced optics, including a Porro prism system and individual focus adjustment, delivering sharp and detailed images in various lighting conditions. Its 8x magnification (minimum 7.6x) and 36mm objective diameter provide a clear and wide field of view, essential for identifying and tracking targets.

Built-in Rangefinder Reticle for Precision Distance Measurement

One of the key features of the Thunderbolt is its built-in Rangefinder Reticle, which allows users to accurately estimate the distance to targets. By comparing the size of the target to the markings on the reticle, users can calculate the distance using the Mil-dot formula, ensuring precise target acquisition.

Understanding the Mil-dot Formula

The Mil-dot formula is a simple but powerful tool for calculating distance. It is based on the principle of angular measurement, where one mil represents an angle of one milliradian, or 1/1000th of a radian. In the context of a Mil-dot reticle, the dots or markings are spaced at one mil intervals, both horizontally and vertically.

To use the Mil-dot formula, you need to know either the size of the target or a portion of it, as well as the angular size of that target in the reticle. Once you have these measurements, you can calculate the distance to the target using the following formula:

Distance = Size of Target / Angular Size of Target * 1000

For example, if a target is 1.8 meters tall and appears to be 4 mils tall in the reticle, you can calculate the distance to the target as follows:

Distance = 1.8 / 4 * 1000 Distance = 450 meters


Enhanced Features for Military Operations

In addition to its Rangefinder Reticle, the Thunderbolt is equipped with a range of features to enhance its performance in the field. The nitrogen-filled housing provides reliable performance in extreme environments, including waterproofing up to 1.5 meters for 30 minutes. The binocular is also tripod-mountable, allowing for extended surveillance operations, while the retractable eye cups ensure comfortable viewing during prolonged missions.

Durability and Reliability for the Toughest Conditions

Weighing 600 grams and encased in a rugged, armor-coated exterior, the Thunderbolt is built to withstand the harshest conditions. Its robust construction ensures long-term durability, making it the ideal optical tool for military professionals operating in challenging environments.

Ideal for Ground Force and Marine Army Operations

Whether used for reconnaissance, surveillance, or target acquisition, the Thunderbolt 8X36 Military Binocular is the ultimate optical tool for ground force and marine army personnel. Its exceptional performance, reliability, and precision make it a valuable asset in any military operation.
